Energy Efficient Directional Routing for Effective Actor-Actor Communication in Wireless Sensor and Actor Networks

Actor-actor communication is an important part of the functioning of Wireless Sensor-Actor Networks (WSANs) and enables the actors to take coordinated action on a given event. Due to various reasons such as actor-mobility and low actor-density, the actor network tends to get partitioned. We propose to use the underlying sensor nodes, which are more densely deployed, to heal these partitions. In order to maximize the utilization of the limited energy available with the sensor nodes, we propose a new routing protocol for actor-actor communication using directional antennas on the actor nodes. Using network simulations, we show that our protocol not only heals the network partitions successfully, but also achieves high throughput and fairness across different flows, in addition to maximizing the network lifetime.
