|Abstract:Wireless sensor network (WSN) brings a new evolution in real-time embedded systems with limited computation, communication, memory, and energy resources that are being used for various applications. The antenna nodes are densely deployed in anenvironment to detect, analyze and monitor the physical phenomenon and consume considerable amount of energy while transmitting the information. It is impractical and sometimes impossible to replace the battery and to maintain longer network life time. So, there is a limitation on the lifetime of the battery power and energy conservation is a challenging issue. Appropriate cluster head (CH) election is one such issue, which can reduce the energy consumption dramatically. Low energy adaptive clustering hierarchy (LEACH) is the most famous hierarchical routing protocol, where the CH selection is in rotation basis based on a probabilistic threshold value and only CHs are allowed to send the information to the base node (BS). But in this proposed approach, a K-hop neighbor clustering protocol is used among the CHs who can easily send the information to the mobile BS by choosing suitable CH descriptors, such as remaining battery power, mobility of BS, and centrality of the clusters. The results have been derived from NS-2 simulator.
