Abstract
A Chain By Division Based on Energy Balance Routing Algorithm (CDEB) is proposed. The algorithm assumes that the network range is a circle
which is divided into 2π/θ regions according to a center angle θ. when forming a chain
a node would decide to whether to join into the chain by comparing the set threshold with the distance between neighbor node and itself. When the chain is completed
chain-head is selected by considering the nodes residual energy、the degree and the distance with the base station. Simulation results show that the algorithm could avoid the produce of the " long- chain"
optimize the status of unbalanced energy consumption and effectively prolong the network life cycle.
