An energy-based weight selection algorithm of monitor node in MANETs

Aiming to solve the problem of security monitor node selection in MANETs, this paper presents an energy-based weight selection algorithm of monitor node. In the scheme, on the one hand, we consider the mutual information as the factor of selecting monitor nodes according to the topological position of the node. On the other hand, the energy consumption of the node is calculated according to the node's energy consumption model, and we consider the residual energy as the factor of selecting monitor nodes. Finally, we consider the mutual information and the residual energy synthetically to calculate the weight of the node by entropy weight method, so as to select monitor nodes. The simulation result shows that the proposed method can reduce the monitoring overhead, improve the network performance, prolong the lifetime and improve the security of networks.
