One of fundamental issues in Wireless Sensor Networks (WSNs) is sensor deployment, which affects the performance and effectiveness of WSNs. Sensor node redeployment is an efficient way to extend the lifetime of the network by deploying additional sensor nodes in the sensing region. In this paper, we formulate the event occurrence probability distribution of the redeployment problem in WSNs as Binomial...
Wireless sensor networks are composed of cheap sensor nodes with limited energy resources. These networks require robust wireless communication protocols that are energy efficient in order to prolong the lifetime of the entire network. This paper studies the routing protocols and analyzes the performance of LEACH (low-energy adaptive clustering hierarchy) in-depth. It is found that the cluster heads...
