Abstract
Opportunistic network is a random network and do not communicate with each other among the respective communication areas. This situation leads to the message transfer process become very difficult. In this paper a reducing energy consumption optimization selection of path transmission routing algorithm (OSPT) in opportunistic networks is proposed. Algorithm is applied to the design of dynamic random network topology, created a dynamic link, optimized and selected the path. It solves the problem of undeliverable messages for a long time in opportunistic networks. According to the simulation experiment and compare with epidemic algorithm and spray and wait algorithm. Experimental results show that OSPT algorithm improves deliver ratio, reduce energy consumption, cache time and transmission delay.
