This document presents information on ad-hoc sensor networks. It discusses that ad-hoc sensor networks are decentralized wireless networks that do not rely on existing infrastructure, with each node participating in routing by forwarding data. The key advantages of ad-hoc sensor networks are that they have no infrastructure requirements and are scalable, mobile, decentralized, and robust. Popular applications of ad-hoc sensor networks include military operations, emergency response, home and personal networks, and environmental monitoring. The document concludes that ad-hoc sensor networks can help cover weaknesses in infrastructure by allowing nodes to self-configure into a network.

3.  A decentralized type of wireless network.
It does not depend on a preexisting
infrastructure.
Each node participates in routing by
forwarding data for other nodes
The determination of which nodes forward
data is made dynamically based on the
network connectivity.
Ad hoc networks can use flooding for
forwarding the data. (distributing algorithm)

5.  No infrastructure and lower cost- Scalable
accommodates the addition of more nodes
 Mobility (MANET only)- Self-configuring, nodes
are also routers
 Decentralized and robust – Independence from
central network administration
 Easy to build and spontaneous infrastructure-
Flexible similar to being able to access the
Internet from many different locations

8.  Mobility in the wireless networks is very
popular now a days. Many peoples in the
street walk and are using small devices like
laptops, or phone to communicate, listening a
music, write SMS, exchanging data with other
people near them, etc.
 The presence of ad hoc wireless sensor
networks covers the infrastructure’s weakness.
Since the ad hoc networks are independent
from infrastructure, the nodes must be able to
work together to establish a greater network.
