Psuedo Randomised Cluster Head Selection Algorithm for Wireless Sensor Network

Recent developments in sensor networks are generally aimed at making wireless sensor networks (WSNs) more viable for implementation in real life scenarios like disaster management, battlefield and border security surveillance etc. Comparable to other wireless networking devices, sensor nodes face acute shortage of battery energy. Many famous existing technologies consider a randomized and distributed clustering strategies to reduce energy consumed by the network, as a whole, and a sensor node, in particular; thereby prolonging the network lifetime of WSNs. Off late concerns have been raised against use of such random approaches. Thus, we came with an idea of redesigning this concept of randomization by including supplementary parameters. This resulted in a pseudo-random scheme wherein network energy decay rate and node depletion rate are decreased by 10-20%, as compared to prevalent policies.
