A Cooperative Broadcast Algorithm Based on the Successful Broadcasting Ratio and Residual Energy of Neighbor Nodes in Mobile Ad Hoc Networks

In order to suppress the broadcast storm, balance the energy consumption of the nodes and provide certain reliability, we propose a cooperative broadcast algorithm based on the successful broadcasting ratio and residual energy of neighbor nodes (BSRREN). In this algorithm, each node in a network calculates the broadcasting coefficient according to the successful broadcasting ratio and residual energy. Then, the broadcasting coefficient encapsulated in the broadcast packets is exchanged between neighbor nodes. Each node constructs a neighbor information table (NIT) to store the broadcasting coefficient. Each node dynamically selects up to four neighbor nodes which have the highest broadcast coefficients as the forwarding nodes. The addresses of the four forwarding nodes which are designated as the next hop forwarding nodes are encapsulated in the broadcast packet headers. The transmissions of each node are randomly delayed to reduce the probability of channel contention and message collision. The simulation results show the BSRREN algorithm has lower forwarding node ratio and higher network lifetime, which indicates the algorithm can effectively suppress broadcast storm and balance the energy consumption.
