In these Wireless data to a fascinated person or user.Sensor Networks, sensor nodes are have an extremely The main aim of an energy-awarelimited power supply. The main aim of this power routing protocol is very critical for these type ofrouting procedure is dangerous for these Wireless Wireless Sensor Networks. Since, the majority of theSensor Networks, because the majority of the sensor’s sensors power is utilized by the communicationpower is utilized at the time of sending the data from a procedure at the time of transmitting or sendingsensor node to the sink or Base Station (BS). In this some data or information from a sensor node to thepaper, we will introduce a new routing protocol calledas MIN-RC, which is mainly based on LEACH-C sink or Base Station(BS). A low power utilizationprotocol to stabilize the power utilization of a variety of routing protocol will prolong the Wireless Sensorsensor nodes to solve the excess power utilization Network life time [1, 2, 3]. In order to prolong theproblem. LEACH-C is a centralized clustering life time of WSN many routing protocols have beenalgorithm, which is based on LEACH[5]. designed to minimize the energy consumed by The LEACH protocol is mainly routing operations [1].used for the purpose of HIERARCHICAL routing. Tosolve the difficulty of power utilization between various Clustering based routing protocols:sensor nodes, MIN-RC uses an adaptive round control Clustering is the procedure, in this themethod to balance the power utilizations by allowingpresent position of the network, cluster dimension, and sensor nodes are ordered in a set about the Clusterthe location of cluster head. To estimate and contrast Head by the task of an observance position and alsoMIN-RC with LEACH-C, we will use ns-2 simulator. inter cluster comparison occupied in the dataThe simulation work completes when the number of processing. In hierarchical (cluster-based) routingnodes are active is less than or equal to the number of protocols, these sensor nodes are categorized into aclusters. practical hierarchy method to structure a many-hops communication representation.

II. ASSOCIATED WORK The Low Energy Adaptive Clustering Hierarchy (LEACH) routing protocol is one of the majority of ordinary routing protocols Fig: Hierarchy of Cluster model which is used for hierarchical routing. This Distribution of power utilization LEACH protocol is introduced to stabilize theamong these nodes can also extend the network life power utilized in these Wireless Sensor Networkstime and also increase the effectiveness of the (WSN) by means of selecting various sensor nodesWireless Sensor Network. Manipulation of a cluster- to perform as cluster heads. These sensor nodesbased routing protocol need to thought of the cluster gather the data from the remaining nodes, and thenarrangement, cluster head selection, data aggregation, aggregate the gathered data, after that transfer thisand also inter and intra- cluster communications [1, aggregated data straightly to the sink or Base2]. The routing protocol LEACH [4, 5] uses a scheme Station (BS). The LEACH protocol functionality iswhere the cluster head is randomly rotated to shown in the following figure:distribute energy consumption among sensor nodesand many researchers attempt to enhance thisprotocol. PEGASIS [3, 6] forms a set of chains ofclosed neighbours with a leader for each chain,each neighbour sends data to its closest neighbouruntil all the data which is sent by the members isaggregated at the chain leader. At that time, thechain leader transmits or sends an aggregated Fig: Functionality of LEACH protocolinformation to the Base Station (BS) as arepresentative of the additional chain members. In This LEACH algorithm partitionTEEN [7] and APTEEN [8] threshold values are the Sensor’s Network life time into differentused to control data transmission.
