Multiratecast in Wireless Fault Tolerant Sensor and Actuator Networks
We study the multicast problem in wireless sensor networks, where the source can send data to a fixed number of destinations (actuators) at a different rate (multiratecast). A typical motivation of such communication scheme is to enable fault tolerant monitoring applications where data is reported to more than one actuators using different rates that decrease with the sensors distance, so that if the closest actuator fails, others can take over from it. We propose two multiratecast routing protocols: Maximum Rate Multicast (MRM) and Optimal Rate Cost Multicast (ORCM), which are the first localized positionbased protocols specifically designed for this problem. The first, MRM, selects the next forwarding neighbor(s) in order to favor destinations requiring the highest rates, while the second, ORCM, evaluates several possible choices and select the best according to a cost over progress ratio criterion. The two protocols are compared by simulation, using a new metric that takes the rate ...
