This document proposes a new routing algorithm called HCIFR for wireless sensor networks that combines hierarchical clustering and iterative filtering. It aims to improve energy efficiency, support dynamic routing during link failures, and provide secure data aggregation. The algorithm initially forms clusters using neighborhood information. Clusterheads, deputy clusterheads, and members are selected. Cluster members transmit data to clusterheads using TDMA. Clusterheads aggregate data using iterative filtering to identify malicious nodes. Deputy clusterheads route aggregated data to the base station. Simulation results show HCIFR performs better than M-LEACH in terms of average energy consumption, throughput, packet drops, and packet delivery.

A QoI Based Energy Efficient Clustering for Dense Wireless Sensor Networkijassn
In a wireless sensor network Quality of Information (QoI), Energy Efficiency, Redundant data avoidance,
congestion control are the important metrics that affect the performance of wireless sensor network. As
many approaches were proposed to increase the performance of a wireless sensor network among them
clustering is one of the efficient approaches in sensor network. Many clustering algorithms concentrate
mainly on power Optimization like FSCH, LEACH, and EELBCRP. There is necessity of the above
metrics in wireless sensor network where nodes are densely deployed in a given network area. As the nodes
are deployed densely there is maximum possibility of nodes appear in the sensing region of other nodes. So
there exists an option that nodes have to send the information that is already reached the base station by its
own cluster members or by members of other clusters. This mechanism will affect the QoI, Energy factor
and congestion control of the wireless sensor networks. Even though clustering uses TDMA (Time Division
Multiple Access) for avoiding congestion control for intra clustering data transmission, but it may fail in
some critical situation. This paper proposed a energy efficient clustering which avoid data redundancy in a
dense sensor network until the network becomes sparse and hence uses the TDMA efficiently during high
density of the nodes.

Wireless sensor network consists of several distributed sensor nodes. It is used for several environmental applications, military applications and health related applications. To prolong the lifetime of the sensor nodes, designing efficient routing protocols is critical. Most of the research in energy efficient data gathering in data centric applications of wireless sensor networks is motivated by LEACH (Low Energy Adaptive Clustering Hierarchy) scheme. It allows the rotation of cluster head role among the sensor nodes and tries to distribute the energy consumption over the network. Selection of sensor node for such role rotations greatly affects the energy efficiency of the network. Some of the routing protocol has a drawback that the cluster is not evenly distributed due to its randomized rotation of local cluster head. We have surveyed several existing methods for selecting energy efficient cluster head in wireless sensor networks. We have proposed an energy efficient cluster head selection method in which the cluster head selection and replacement cost is reduced and ultimately the network lifetime is increased. Using our proposed method, network life time is increased compared to existing methods. Keywords: WSN, CH, BS, LEACH, LEACH-B, LEACH-F

paper compared the performance analysis of some existing routing protocols for target tracking
application with proposed hierarchical binary tree structure to store the routing information. The sensed
information is stored in controlled way at multiple sensor nodes (e.g. node, parent node and grandparent
node) which deployed using complete binary tree data structure. This reduces traffic implosion and
geographical overlapping. Simulation result showed improved network lifetime by 20%, target detection

Throughput analysis of energy aware routing protocol for real time load distr...eSAT Journals
Abstract Wireless sensor network (WSNs) are self-organized systems that depend on highly distributed and scattered low cost tiny devices. These devices have some limitations such as processing capability, memory size, communication distance coverage and energy capabilities. In order to maximize the autonomy of individual nodes and indirectly the lifetime of the network, most of the research work is done on power saving techniques. Hence, we propose energy-aware load distribution technique that can provide an excellent data transfer of packets from source to destination via hop by hop basis. Therefore, by making use of the cross-layer interactions between the physical layer and the network layer thus leads to an improvement in energy efficiency of the entire network when compared with other protocols and it also improves the response time in case of network change. Keywords:- wireless sensor network, energy-aware, load distribution, power saving, cross layer interactions.

INCREASING WIRELESS SENSOR NETWORKS LIFETIME WITH NEW METHODijwmn
One of the most important issues in Wireless Sensor Networks (WSNs) is severe energy restrictions. As the
performance of Sensor Networks is strongly dependence to the network lifetime, researchers seek a way to
use node energy supply effectively and increasing network lifetime. As a consequence, it is crucial to use
routing algorithms result in decrease energy consumption and better bandwidth utilization. The purpose of
this paper is to increase Wireless Sensor Networks lifetime using LEACH-algorithm. So before clustering
Network environment, it is divided into two virtual layers (using distance between sensor nodes and base
station) and then regarding to sensors position in each of two layers, residual energy of sensor and
distance from base station is used in clustering. In this article, we compare proposed algorithm with wellknown LEACH and ELEACH algorithms in homogenous environment (with equal energy for all sensors)
and heterogeneous one (energy of half of sensors get doubled), also for static and dynamic situation of base
station. Results show that our proposed algorithm delivers improved performance.
Energy aware clustering protocol (eacp)IJCNCJournal
Energy saving to prolong the network life is an important design issue while developing a new routing
protocol for wireless sensor network. Clustering is a key technique for this and helps in maximizing the
network lifetime and scalability. Most of the routing and data dissemination protocols of WSN assume a
homogeneous network architecture, in which all sensors have the same capabilities in terms of battery
power, communication, sensing, storage, and processing. Recently, there has been an interest in
heterogeneous sensor networks, especially for real deployments. This research paper has proposed a new
energy aware clustering protocol (EACP) for heterogeneous wireless sensor networks. Heterogeneity is
introduced in EACP by using two types of nodes: normal and advanced. In EACP cluster heads for normal
nodes are elected with the help of a probability scheme based on residual and average energy of the
normal nodes. This will ensure that only the high residual normal nodes can become the cluster head in a
round. Advanced nodes use a separate probability based scheme for cluster head election and they will
further act as a gateway for normal cluster heads and transmit their data load to base station when they
are not doing the duty of a cluster head. Finally a sleep state is suggested for some sensor nodes during
cluster formation phase to save network energy. The performance of EACP is compared with SEP and
simulation result shows the better result for stability period, network life and energy saving than SEP.
Maximizing Lifetime of Homogeneous Wireless Sensor Network through Energy Eff...CSCJournals
The objective of this paper is to develop a mechanism to increase the lifetime of homogeneous wireless sensor networks (WSNs) through minimizing long range communication, efficient data delivery and energy balancing. Energy efficiency is a very important issue for sensor nodes which affects the lifetime of sensor networks. To achieve energy balancing and maximizing network lifetime we divided the whole network into different clusters. In cluster based architecture, the role of aggregator node is very crucial because of extra processing and long range communication. Once the aggregator node becomes non functional, it affects the whole cluster. We introduced a candidate cluster head node on the basis of node density. We proposed a modified cluster based WSN architecture by introducing a server node (SN) that is rich in terms of resources. This server node (SN) takes the responsibility of transmitting data to the base station over longer distances from the cluster head. We proposed cluster head selection algorithm based on residual energy, distance, reliability and degree of mobility. The proposed method can save overall energy consumption and extend the lifetime of the sensor network and also addresses robustness against even/uneven node deployment.
Clustering provides an effective method for
extending the lifetime of a wireless sensor network. Current
clustering methods selecting cluster heads with more residual
energy, and rotating cluster heads periodically to distribute the
energy consumption among nodes in each cluster. However,
they rarely consider the hot spot problem in multi hop sensor
networks. When cluster heads forward their data to the base
station, the cluster heads closer to the base station are heavily
burdened with traffic and tend to die much faster. To mitigate
the hot spot problem, we propose a Novel Energy Efficient
Unequal Clustering Routing (NEEUC) protocol. It uses residual
energy and groupsthe nodesinto clusters of unequal layers

All information collected, as well as related requests, will be handled as carefully and efficiently as possible in accordance with IJCER standards for integrity and objectivity.

An Adaptive Energy Aware Clustering Based Reliable Routing for in-Network Agg...Editor IJCATR
Wireless Sensor Network (WSN) consists of spatially distributed autonomous devices that cooperatively sense physical or
environmental conditions. Due to the non-uniform node deployment, the energy consumption among nodes are more
imbalanced in cluster-based wireless sensor networks this factor will affect the network life time. Cluster-based routing and EADC
algorithm through an efficient energy aware clustering algorithm is employed to avoid imbalance network distribution. Our proposed
protocol EADC aims at minimizing the overall network overhead and energy expenditure associated with the multi hop data retrieval
process while also ensuring balanced energy consumption among SNs and prolonged network life time .A optimal one-hop based
selective node in building cluster structures consisted of member nodes that route their measured data to their assigned cluster head is
identified to ensure efficient communication. The proposed routing algorithm increases forwarding tasks of the nodes in scarcely
covered areas by forcing cluster heads to choose nodes with higher energy and fewer member nodes and finally, achieves
imbalanced among cluster head and improve the network life time.
Performance evaluation of data filtering approach in wireless sensor networks...ijmnct
Wireless Sensor Network is a field of research which is viable in every application area like security
services, patient care, traffic regulations, habitat monitoring and so on. The resource limitation of small
sized tiny nodes has always been an issue in wireless sensor networks. Various techniques for improving
network lifetime have been proposed in the past. Now the attention has been shifted towards heterogeneous
networks rather than having homogeneous sensor nodes in a network. The concept of partial mobility has
also been suggested for network longevity. In all the major proposals; clustering and data aggregation in
heterogeneous networks has played an integral role. This paper contributes towards a new concept of
clustering and data filtering in wireless sensor networks. In this paper we have compared voronoi based
ant systems with standard LEACH-C algorithm and MTWSW with TWSW algorithm. Both the techniques
have been applied in heterogeneous wireless sensor networks. This approach is applicable both for critical
as well as for non-critical applications in wireless sensor networks. Both the approaches presented in this
paper outperform LEACH-C and TWSW in terms of energy efficiency and shows promising results for
future work.
This paper considers a heterogeneous network of energy constrained sensors deployed over a region. Each
Normal sensor node in a network is systematically gathering and transmitting sensed data to the clusterhead,
and then cluster head sending data to a base station (via intermediate cluster- heads). This paper
focuses on reducing the energy consumption and hence improving lifetime of wireless sensor Networks.
Clustering sensor node is an effective topology for the energy constrained networks. So energy saving
algorithm has been developed in which clusters are formed considering a subset of high energy nodes as a
cluster-head and another subset of powerful nodes is ask to go to sleep. When Cluster heads deplete their
energy another subset of nodes becomes active and acts as a cluster head. Proposed approach is
implemented in MATLAB, Simulation results shows that it can prolong the network lifetime than LEACH
protocol, and achieves better performance than the existing clustering algorithms such as LEACH.
ENERGY EFFICIENT GRID AND TREE BASED ROUTING PROTOCOLijwmn
In Wireless Sensor Network, a large number of sensor nodes are deployed and they mainly consume energy
in transmitting data over long distances. Sensor nodes are battery powered and their energy is restricted.
Since the location of the sink is remote, considerable energy would be consumed if each node directly
transmits data to the base station. Aggregating data at the intermediate nodes and transmitting using multihops
aids in reducing energy consumption to a great extent. This paper proposes a hybrid protocol
“Energy efficient Grid and Tree based routing protocol” (EGT) in which the sensing area is divided into
grids. The nodes in the grid relay data to the cell leader which aggregates the data and transmits to the
sink using the constructed hop tree. Simulation results show that EGT performs better than LEACH.
An Improved Energy Efficient Wireless Sensor Networks Through Clustering In C...Editor IJCATR
One of the major reason for performance degradation in Wireless sensor network is the overhead due to control packet and
packet delivery degradation. Clustering in cross layer network operation is an efficient way manage control packet overhead and which
ultimately improve the lifetime of a network. All these overheads are crucial in a scalable networks. But the clustering always suffer
from the cluster head failure which need to be solved effectively in a large network. As the focus is to improve the average lifetime of
sensor network the cluster head is selected based on the battery life of nodes. The cross-layer operation model optimize the overheads
in multiple layer and ultimately the use of clustering will reduce the major overheads identified and their by the energy consumption
and throughput of wireless sensor network is improved. The proposed model operates on two layers of network ie., Network Layer
and Transport Layer and Clustering is applied in the network layer . The simulation result shows that the integration of two layers
reduces the energy consumption and increases the throughput of the wireless sensor networks.

An Adaptive Energy Aware Clustering Based Reliable Routing for in-Network Agg...Editor IJCATR
Wireless Sensor Network (WSN) consists of spatially distributed autonomous devices that cooperatively sense physical or
environmental conditions. Due to the non-uniform node deployment, the energy consumption among nodes are more
imbalanced in cluster-based wireless sensor networks this factor will affect the network life time. Cluster-based routing and EADC
algorithm through an efficient energy aware clustering algorithm is employed to avoid imbalance network distribution. Our proposed
protocol EADC aims at minimizing the overall network overhead and energy expenditure associated with the multi hop data retrieval
process while also ensuring balanced energy consumption among SNs and prolonged network life time .A optimal one-hop based
selective node in building cluster structures consisted of member nodes that route their measured data to their assigned cluster head is
identified to ensure efficient communication. The proposed routing algorithm increases forwarding tasks of the nodes in scarcely
covered areas by forcing cluster heads to choose nodes with higher energy and fewer member nodes and finally, achieves
imbalanced among cluster head and improve the network life time.
Performance evaluation of data filtering approach in wireless sensor networks...ijmnct
Wireless Sensor Network is a field of research which is viable in every application area like security
services, patient care, traffic regulations, habitat monitoring and so on. The resource limitation of small
sized tiny nodes has always been an issue in wireless sensor networks. Various techniques for improving
network lifetime have been proposed in the past. Now the attention has been shifted towards heterogeneous
networks rather than having homogeneous sensor nodes in a network. The concept of partial mobility has
also been suggested for network longevity. In all the major proposals; clustering and data aggregation in
heterogeneous networks has played an integral role. This paper contributes towards a new concept of
clustering and data filtering in wireless sensor networks. In this paper we have compared voronoi based
ant systems with standard LEACH-C algorithm and MTWSW with TWSW algorithm. Both the techniques
have been applied in heterogeneous wireless sensor networks. This approach is applicable both for critical
as well as for non-critical applications in wireless sensor networks. Both the approaches presented in this
paper outperform LEACH-C and TWSW in terms of energy efficiency and shows promising results for
future work.
This paper considers a heterogeneous network of energy constrained sensors deployed over a region. Each
Normal sensor node in a network is systematically gathering and transmitting sensed data to the clusterhead,
and then cluster head sending data to a base station (via intermediate cluster- heads). This paper
focuses on reducing the energy consumption and hence improving lifetime of wireless sensor Networks.
Clustering sensor node is an effective topology for the energy constrained networks. So energy saving
algorithm has been developed in which clusters are formed considering a subset of high energy nodes as a
cluster-head and another subset of powerful nodes is ask to go to sleep. When Cluster heads deplete their
energy another subset of nodes becomes active and acts as a cluster head. Proposed approach is
implemented in MATLAB, Simulation results shows that it can prolong the network lifetime than LEACH
protocol, and achieves better performance than the existing clustering algorithms such as LEACH.
ENERGY EFFICIENT GRID AND TREE BASED ROUTING PROTOCOLijwmn
In Wireless Sensor Network, a large number of sensor nodes are deployed and they mainly consume energy
in transmitting data over long distances. Sensor nodes are battery powered and their energy is restricted.
Since the location of the sink is remote, considerable energy would be consumed if each node directly
transmits data to the base station. Aggregating data at the intermediate nodes and transmitting using multihops
aids in reducing energy consumption to a great extent. This paper proposes a hybrid protocol
“Energy efficient Grid and Tree based routing protocol” (EGT) in which the sensing area is divided into
grids. The nodes in the grid relay data to the cell leader which aggregates the data and transmits to the
sink using the constructed hop tree. Simulation results show that EGT performs better than LEACH.

One of the major reason for performance degradation in Wireless sensor network is the overhead due to control packet and

Wireless sensor networks are widely considered as one of the most important technologies. The Wireless Sensor Network (WSN) is a wireless network consisting of ten to thousand small nodes with sensing, computing and wireless communication capabilities. They have been applied to numerous fields such as healthcare, monitoring system, military, and so forth. Recent advances in wireless sensor networks have led to many new protocols specifically designed for sensor networks where energy awareness is an essential consideration. Energy efficiency is thus a primary issue in maintaining the network. Innovative techniques that improve energy efficiency to prolong the network lifetime are highly required. Clustering is an effective topology control approach in wireless sensor networks. This paper elaborates several techniques like LEACH, HEED, LEACH-B, PEACH, EEUC of cluster head selection for energy efficient in wireless sensor networks.
INCREASING WIRELESS SENSOR NETWORKS LIFETIME WITH NEW METHODijwmn
One of the most important issues in Wireless Sensor Networks (WSNs) is severe energy restrictions. As the
performance of Sensor Networks is strongly dependence to the network lifetime, researchers seek a way to
use node energy supply effectively and increasing network lifetime. As a consequence, it is crucial to use
routing algorithms result in decrease energy consumption and better bandwidth utilization. The purpose of
this paper is to increase Wireless Sensor Networks lifetime using LEACH-algorithm. So before clustering
Network environment, it is divided into two virtual layers (using distance between sensor nodes and base
station) and then regarding to sensors position in each of two layers, residual energy of sensor and
distance from base station is used in clustering. In this article, we compare proposed algorithm with wellknown LEACH and ELEACH algorithms in homogenous environment (with equal energy for all sensors)
and heterogeneous one (energy of half of sensors get doubled), also for static and dynamic situation of base
station. Results show that our proposed algorithm delivers improved performance.

Energy Conservation in Wireless Sensor Networks Using Cluster-Based ApproachIJRES Journal
In a wireless networking environment, the network is comprised of sensor nodes and backbones are subsets of sensors or actuators that suffice for performing basic data communication operations. They are applied for energy efficient broadcasting. In a broadcasting (also known as data dissemination) task, a message is to be sent from one node, which could be a sink or an actuator, to all the sensors or all the actuators in the network. The goal is to minimize the number of rebroadcasts while attempting to deliver messages to all sensors or actuators. Neighbor detection and route discovery algorithms that consider a realistic physical layer are described. An adaptive broadcasting protocol without parameters suitable for delay tolerant networks is further discussed. In existing solutions for minimal energy broadcasting problem, nodes can adjust their transmission powers. Wireless Sensor Networks (WSNs) are sets of many sensors that gather data and collaborate together. So, the procedures of broadcast or multicast are more important than traditional point-to-point communication in computer network. This paper focuses on broadcasting in structured WSNs. In such a kind, the procedure of network communications is easier than in unstructured WSNs. Thus, it will make an overview of Multi Point Relay (MPR) to show its weakness. Then define a cluster-based architecture for WSNs which is constructed using MPR. Next, provide a new broadcast algorithm based on the previous cluster architecture called 3B (Backbone Based Broadcasting). By the end, an illustration of 3B shows that it minimizes the energy consumption for accomplishing broadcast compared to MPR.
A New Method for Reducing Energy Consumption in Wireless Sensor Networks usin...Editor IJCATR
Nowadays, wireless sensor networks, clustering protocol based on the neighboring nodes into separate clusters and fault
tolerance for each cluster exists for sensors to send information to the base station, to gain the best performance in terms of increased
longevity and maintain tolerance than with other routing methods. However, most clustering protocols proposed so far, only
geographical proximity (neighboring) cluster formation is considered as a parameter. In this study, a new clustering protocol and fault
tolerance based on the fuzzy algorithms are able to clustering nodes in sensor networks based on fuzzy logic and fault tolerance. This
protocol uses clustering sensor nodes and fault tolerance exist in the network to reduce energy consumption, so that faulty sensors
from neighboring nodes are used to cover the errors, work based on the most criteria overlay neighbor sensors with defective sensors,
distance neighbor sensors from fault sensor and distance neighbor sensors from central station is done. Superior performance of the
protocol can be seen in terms of increasing the network lifetime and maintain the best network tolerance in comparison with previous
protocols such as LEACH in the simulation results.
Data gathering in wireless sensor networks using intermediate nodesIJCNCJournal
Energy consumption is an essential concern to Wireless Sensor Networks (WSNs).The major cause of the energy consumption in WSNs is due to the data aggregation. A data aggregation is a process of collecting data from sensor nodes and transmitting these data to the sink node or base station. An effective way to perform such a task is accomplished by using clustering. In clustering, nodes are grouped into clusters where a number of nodes, called cluster heads, are responsible for gathering data from other nodes, aggregate them and transmit them to the Base Station (BS).
In this paper we produce a new algorithm which focused on reducing the transmission bath between sensor nodes and cluster heads. A proper utilization and reserving of the available power resources is achieved with this technique compared to the well-known LEACH_C algorithm.

This paper presents, a Group Based Optimal Retransmission Medium Access (GORMA) Protocol is
designed that combines protocol of Collision Avoidance (CA) and energy management for low-cost, shortrange,
low-data rate and low-energy sensor nodes applications in environment monitoring, agriculture,
industrial plants etc. In this paper, the GORMA protocol focuses on efficient MAC protocol to provide
autonomous Quality of Service (QoS) to the sensor nodes in one-hop QoS retransmission group and two
QoS groups in WSNs where the source nodes do not have receiver circuits. Hence, they can only transmit
data to a sink node, but cannot receive any control signals from the sink node. The proposed protocol
GORMA provides QoS to the nodes which work independently on predefined time by allowing them to
transmit each packet an optimal number of times within a given period. Our simulation results shows that
the performance of GORMA protocol, which maximize the delivery probability of one-hop QoS group and
two QoS groups and minimize the energy consumption.

The most emerging prominent sensor network applications collect data from sensor nodes and monitors
periodically. Resource constraint Sensor motes sense the environment and transit data to the remote sink
via multiple hops. Minimum energy dissipation and secure data transmission are crucial to such
applications. This paper delivers an energy efficient, lifetime improving, secure periodic Data Gathering
scheme that is a hybrid of heuristic path establishment and secure data transmission. This protocol uses
artificial intelligence (AI) based A* heuristic search algorithm to establish energy efficient admissible
optimal path to sink in terms of high residual energy, minimum hop counts and high link quality. This
scheme also adopts block encryption Rivest Cipher (RC6) Algorithm to secure the transmission of packets.
This code and speed optimized block encryption provides confidentiality against critical data and
consumes less energy for encryption. This proposed method increases the network lifetime there by
reducing the total traffic load. Evaluation of performance analysis of this algorithm using Network

I. INTRODUCTION
A WSN is a collection of sensor nodes and a small
number of data collection devices. The sensor nodes are
low cost, low-power, small-size devices, and are used for
sensing applications like temperature recording, military
surveillance, fire detection etc. The sensor nodes are used
for gathering information which is present in environment
of their interest. The sensor nodes send their sensed
information using a wireless medium to a remote base
station (sink). The base station aggregates the collected
data and draw conclusions over sensed data.
Routing is an important and challenging design issue
need to considered for WSN. “A properly designed
routing protocol should not only ensure high message
delivery ratio and low energy consumption for message
delivery, but also balance the entire sensor network
energy consumption, and thereby extend the sensor
network lifetime.” The main feature of WSNs are:
scalability, self-organization, self-healing, energy
efficiency, network lifetime optimization, less
complexity, less costly, security, routing, size of nodes
and connectivity between the sensor nodes. Every sensor
node in the network should be a source or destination but
not both.
HCIFR protocol has the advantages:
HCIFR ensures that the energy consumption of
the wireless sensor network can be reduced. So
that the maximization of network lifetime can be
achieved.
HCIFR algorithm takes routing decisions
dynamically. So the data delivery to the
clusterhead and finally to the base station.
HCIFR uses the Iterative Filtering algorithm for
secure data aggregation.
Clustering is concept used in the proposed system for
the reduction of energy consumption. Clustering means
grouping the different set of nodes which are their
neighbours. Cluster members can send their sensed data
to the clusterhead with less energy consumption. The
clusterhead can send the final aggregated data to the base
station. The clusterhead is responsible for collecting data,
checking for the redundancy and aggregate the remaining
data. The aggregated data can be transmitted to the base
station.
The data can be aggregated using the averaging
technique by clusterhead. Through this technique there
are possibilities of security attacks on sensor nodes whose
battery power is dead. So to avoid these type of attacks,
the Iterative Filtering (IF) algorithms are used.
This paper is coordinated by: section 2: explains
literature survey, and different routing algorithms. Section
3: contains methodology of proposed system which
includes dynamic hierarchical clustering and iterative
filtering. Section 4: depicts the results obtained from
evaluation of the proposed system. Section 5:
conclusions.

clusterhead, two deputy clusterhead, and cluster members.
The role selection of the sensor is done by base station
using the cumulative credit point [1]. Mohsen Rezvani,
Aleksandar Ignjatovic, Elisa Bertino and Sanjay Jha
proposed a system which is an improvement of Iterative
Filtering algorithm. This algorithm is collusion robust
against security attacks. The algorithm used to find the
error rate by calculating the bias and variance of each
sensor node and eliminate the error rate using the MLE.
The malicious nodes are blocked by the clusterhead and

deputy clusterhead [3].
In this paper [4], S. Lindsey and C. S. Raghavendra
proposed an algorithm called PEGASIS (control
proficient assembling in sensor data frameworks), a close
ideal chain-based convention that is a changeover
LEACH. In PEGASIS, every node connects to its nearby
neighbour and alternates transmitting to the base station,
in this way decreasing the energy spent per round. In this
paper [5] D. B. Johnson, and D. A. Maltz proposed an
algorithm routing the packets between the mobile wireless
hosts in adhoc network. This algorithm is capable of
adapting of frequently changing the paths dynamically at
the time of link failure or link unavailability. The paths
are changed when there is overhead. In this paper [6] J. N.
Al-Karaki and A. E. Kamal have surveyed on the routing
challenges, design issues while designing the routing
protocols. The basics of the routing, routing types and
routing protocols have been covered under this survey.
In this paper [7] A. Manjeshwar and D. P. Agarwal
proposed an energy efficient algorithm called TEEN
(Threshold sensitive Energy Efficient sensor Network
protocol). There are many algorithms based on network
classification like reactive and proactive networks. TEEN
is been mainly proposed for reactive type of networks.
Evaluate the performance of the protocol for a simple
temperature sensing application. In terms of energy
efficiency, this protocol outperforms from all existing
sensor network protocols. TEEN perform much better
than LEACH. In this paper [8] “A. Manjeshwar and D. P.
Agarwal” has proposed an improvised version of TEEN
algorithm called APTEEN (A hybrid protocol for efficient
routing and comprehensive information retrieval in
wireless sensor networks). This algorithm combines all
the best features present in reactive and proactive
networks. It collects the data periodically and also give
real-time warnings when there are critical events. This
algorithm can also be extended further to sensor networks
with uneven node distributions.
In this paper [9] I. F. Akyildiz, W. Su, Y.
Sankarasubramaniam, and E. Cayirci has done survey on
sensor networks. The basics of the sensor networks,
network creation, protocol stack, and different types of

These all concepts is explained in detail. In this paper [10]
W. Heinzelman, A. Chandrakasan, and H. Balakrishnan
has proposed an algorithm called Energy-efficient
communication protocol for wireless microsensor
networks. The energy consumption can be reduced by
using this algorithm. The clustering concept is used for
energy consumptioj reduction and also the load on one
clusterhead is been reduced by sharing the load to other
clusterheads.

A. Self-Organizing Phase: Once the clusters are formed
as per the neighbourhood, the role selection of the
sensor node can be clusterhead and deputy
clusterheads will be done in this phase. The selection
will be done by base station using the Cumulative
Credit Point. Cumulative Credit Point is a
combination of three values is: energy of the node,
node degree and the mobility. The corresponding
weight will calculated using these three values. The
cumulative credit point of the nodes are arranged in
descending order. The first threshold value will be
selected as a clusterhead, second and third highest
threshold values will be selected as deputy
clusterheads. The clusterhead is involved in data
collection from their cluster members. The
clusterhead shares its data to one of the deputy
clusterhead. The deputy clusterhead is involved in
data transmission. It will forward the data to the base
station by connecting deputy clusterheads of other
clusters.

Access) is used to send the data from cluster
members to its clusterhead, and the clusterhead share
its data to deputy clusterhead. The base station also
receives the data from the deputy clusterhead in
TDMA.
C. Secure Data aggregation using Iterative Filtering
Phase: The data received from its cluster members
will be aggregated using the iterative filtering
algorithm. If the sensor nodes send the incorrect data
then the clusterhead identifies the node which has
sent incorrect data by calculating the Bias value of
each sensor node (Error rate is calculated), the
Variance value of each sensor node (noise ratio is
calculated) and using the MLE (Maximum
Likelihood Estimator). The MLE finds the original
signal or data from Bias and Variance value. In this
way, the clusterhead finds the original data and
aggregates with the data sent by other cluster
members.
D. Data Transfer Phase: this is the phase where the
final aggregated reaches its destination called Base
station: Finally the aggregated data is shared by
clusterhead to its deputy clusterhead. The deputy
clusterhead forward the data to the base station by
connecting the different and nearest deputy
clusterhead of other clusters.
E. Exception Handling Phase: This phase specifies
how to handle in situations like link failure, and
clusterhead is not able to withstand its position. At
the time of link failure, alternative routes will are
used by the deputy clusterheads or cluster members
to send the data. The routes are calculated
dynamically. When the energy of the clusterhead is
reduced in such a way that it cannot collect the data
then the clusterheadship is transferred to one of its
deputy clusterhead. The deputy clusterhead for that
cluster will be selected by base station.
IV. RESULTS AND DISCUSSION
The NS2 network simulator is used. Consider a
sensor network of 82 sensor nodes deployed randomly in
the field as shown in below fig. The routing algorithm is
verified for different network scenarios. The results of the
proposed routing algorithm are also compared with the
results of other algorithm. M-LEACH protocol is selected
to compare with the proposed protocol by considering the
mobility of nodes while routing the packets.

The sensor node 0 is sending the hello packets to its
neighbours inturn the neighbours will broadcast the
“Hello” packets to its neighbours as shown in below fig 3

nearest neighbours to find the neighbourhood
The sensor nodes have formed different clusters in which
each color represents one cluster as shown in below fig 4.
Fig 4: Nodes have formed different clusters
The sensor nodes of each cluster declare its
clusterhead and deputy clusterhead1 and deputy
clusterhead2 has been selected based on the cumulative
credit point. For example the blue cluster which is at
rightmost top corner, the cluster consists of 74, 75, 76, 77,
78, 79, and 80. Based on the threshold value of the node
78 is selected as clusterhead. The deputy clusterhead1 is
75 and deputy clusterhead2 74 as shown in below fig 5.

clusters are declared
The iterative filtering algorithm is used to find
malicious or misbehaved node in the wireless sensor
network. For example node number 1, 2, 14 and so on are
malicious node as shown in below fig 6.

station. The comparison of both algorithms is shown in
the form of graph as in fig 7.
Fig 7: Comparison of M-LEACH algorithm and HCIFR
algorithm based on energy consumption
Throughput: It is the ratio between the actual numbers of
packets transmitted by the nodes in the system to the
numbers of successfully delivered packets at the base
station. A protocol with higher throughput is desirable.”
The graph is shown in fig 8 how the throughput based on
speed of delivery is varies from the proposed algorithm to
M-LEACH algorithm.
Fig 8: Comparison of M-LEACH algorithm and HCIFR
algorithm based on throughput
Packet drops: Packet loss occurs due to the computer
network failure while the packets reaching to its
destination. The packet drops of the HCIFR algorithm are
compared to the M-LEACH algorithm as shown in below
fig 9.
Fig 9: Comparison of M-LEACH algorithm and HCIFR
algorithm based on packet drops
Packet delivery: The successful delivery of a packet over
a wireless sensor network depends on the routing
algorithm used to route the packets. The packet delivery
of the HCIFR algorithm is compared to the packet
delivery of the M-LEACH algorithm is shown in fig 10.

algorithm based on packet delivery to the base station
V. CONCLUSION
An energy efficient routing algorithm is proposed for
efficient routing of the sensed data from the cluster
members to its clusterhead, then clusterhead aggregates
the data using the Iterative Filtering algorithm which is
collusion robust and checks for trustworthiness. Then the
data from clusterhead shares with its one of the deputy
clusterhead and finally to the Base station. The proposed
algorithm is also fault tolerant. The proposed routing
algorithm outperforms when compared to the M-LEACH
algorithm.
