Improving Directional Rumor Routing in Wireless Sensor Networks

Rumor routing is a classic routing algorithm based on the movement of the software agents among the network. In directional rumor routing, we try to propagate agents in straight lines instead of randomly wandering around the source point leading to definitely better performance. In this paper we try to augment the traditional directional rumor routing by introducing a second layer geographical routing. Moreover, a method is proposed to reduce the cost of localization equipments by using cheaper equipments like AoA antennas. Finally, the new protocol is evaluated by simulation.
