ABSTRACT:
Clustering algorithms can balance the power consumption of energy constraint
wireless sensor networks. This paper proposes a new clustering protocol
called Mean Territorial Energy Based Clustering Protocol (MTEP) for
randomly deployed wireless sensor networks. In MTEP, cluster heads are selected
according to residual energy and location information of a node in
current round as well as mean territorial energy and total base station distance
of node’s corresponding cluster territory in previous round. Energy consumption
in conventional protocols becomes unbalanced because of clusters having
different lengths. Proposed MTEP protocol addresses this problem by setting
thresholds on cluster length and node to cluster head distance for producing
equal length clusters. Simulation results show that MTEP protocol extends
network lifetime and stability with reduction in energy dissipation compared
to other clustering protocols such as LEACH and REAC.
