Abstract
There does not exit a complete transmission path in the opportunistic network. In order to further improve the delivery rate and transmission delay, hybrid routing algorithms with node utility and redundancy was proposed, but they face the problem of higher network overhead. In addition, data transmission consumes energy while the energy of node is limited. Therefore, efficient nodes may lead to energy depletion due to excessive data transmission, aggravating the network disconnection. Considering this fact, a routing algorithm based on node utility and energy is proposed, which takes into account the influence of self-difference and dynamic variation of node relationship on routing packets, and makes full use of social relations to calculate the social utility of nodes, and synthesizes the node’s residual energy to evaluate the node’s forwarding capability, so as to make balance between communication overhead and energy consumption. Finally, compared with other algorithms, the proposed routing scheme can achieve better packet delivery rate and transmission delay, while network overhead and energy balance are greatly improved.
