IDDR: Improved Density Controlled Divide-and-Rule Scheme for Energy Efficient Routing in Wireless Sensor Networks

In Wireless Sensor Networks (WSNs) unbalanced energy consumption is a major problem. As a result, energy hole is created and network lifetime is reduced. In this paper, we propose IDDR to avoid the energy hole creation through uniform energy consumption. Proposed scheme reduces coverage and energy hole by dividing the network into small segments with static number of Cluster Heads (CHs) in each round. Selection of CH in each segment is based on maximum residual energy. Simulation results prove that proposed protocol outperforms the compared protocols.
