A Novel Self Organizing Framework for SANETs

Sensor application requirements vary tremendously, ranging from densely deployed habitat-monitoring setup to the real-time constrained military applications. This paper presents the design of a novel self-organizing framework for SANETs (Sensor and Actuator Networks). We assume two wireless interfaces at the actuator nodes, one to communicate with sensor nodes, and the other, for the neighboring actuator nodes for fast and effective actuation process. We design a new protocol called ADP (Actuator Discovery protocol) which provides an optimal attachment for a sensor node to the nearest actuator. For the sensor-actuator coordination, the proposed ADP can guarantee ordering, synchronization and eliminates the redundancy of actions. It also renders the sensor and actuator nodes with the ability to self-organize and to exploit the spatial and temporal correlations in an efficient way. A new node-addressing scheme is proposed to make the routing more powerful especially in case of node failure and mobility.
