Abstract
In this paper, M-SEP (Modified Stable Election Protocol) is proposed for electing cluster heads in a distributed fashion in two, three and up to ninth level hierarchical wireless sensor networks. The significant improvement has been seen using M-SEP in comparison with SEP in terms of network lifetime, energy consumption and data transmission to BS. The simulation results are compared and analysis is done to see the scope of future work. The superior characteristic of this protocol is discussed by describing the probability equations for multi level M-SEP. Here two aggregators are introduced along with one sink in the centre. The results reveal that there is 200 % improvement in the overall lifetime of the network by using M-SEP after comparing two-level, three-level and up to ninth level network hierarchy. Two aggregators are placed at different coordinates and results are compiled. This work also recommends a final placement of the gathering nodes for best results. The investigations ascertain that network lifetime and efficiency increases by using M-SEP over SEP.
