Reduction of exploratory data messages on directed diffusion in mobile wireless sensor networks

In directed diffusion, sensor nodes send interest/exploratory data messages for setting up paths by flooding. This flooding approach consumes high amount of energy in the network. Accordingly, some research work in the literature studies how to solve this flooding problem focusing on the interest messages. Little work has been done on reducing the exploratory data. In this paper, we propose a new routing scheme by modifying the original directed diffusion to reduce the number of the exploratory data messages. The numerical results from simulation show that our proposed scheme can reduce the number of exploratory data message and consumes energy less than the original directed diffusion protocol.
