With the advent of location aware sensor applications, precise location discovery has become an important technology in wireless sensor networks. Inter Peer communication in the sensor network has been modeled as the graph with constraints defined in terms of proximity. Recurrent grid based voting approach (RGBV) has been introduced to estimate the location of unknown nodes in the network. Voting...
One of the widely used security mechanism for sensor network is the software-hardware implementation of cryptographic algorithms. If the confidential data is lost as a result of adversary effect, then the whole sensor network is prone to get exposed to the intruder. What we need is a strong mechanism, to protect such sensitive data. In this paper we present a technique where we mask all the intermediate...
A wireless sensor network typically consists of a dense deployment of sensor nodes to achieve higher resolution and better network coverage. Having a dense network increases the fault-tolerance and robustness of the system. However, if not properly handled, it can lead to more collisions during transmission and also network congestion. Furthermore, wireless communication is inherently unpredictable...
