Source to Multiple Sink Capacity Related Reliability of Wireless Sensor Networks

Present day communication in wireless sensor networks have become complex. They collect information from the neighboring sensors and transmit it to only one sink node. Network with only one sink node is simple to be implemented but with multiple sink nodes few complications arises which includes node failure and energy-hole problems. The presumption of connectivity in present day networks is not justifiable as these networks are bandwidth/flow limited. This work has the capability of computing CRR (Capacity related reliability) of source to multiple sinks of network. Source to Multiple sink means the required amount of information should be transmitted to the sensors of a network from its source. The proposed method is applied in three steps. First step assumes the knowledge of spanning trees. Second step involves formation of successful spanning trees which fulfill the capacity requirement at all the terminal sensor nodes. With knowledge of these, CRR of the network with source to multiple sinks has been determined and compared with other methods.
