General Sink Location Service Based on Circle and Line Paths in Wireless Sensor Networks

In wireless sensor networks, a geographic routing requests source nodes (sensor nodes) to know location information of destination nodes (sinks) to send their data. To address this issue, many sink location service schemes have been proposed in the literature. They are designed to support only one communication mode such as unicast, anycast, manycast, or multicast communication modes. However, because an application can have one or more communication modes or a sensor network can operate several applications with each communication mode, it is necessary for a scheme to support all communication modes. Hence, we propose a general sink location service scheme for supporting all communication modes. The proposed scheme modifies the basic idea of the existing one proposed for unicast communication mode and extends it for supporting all communication modes. Simulation results show that the proposed scheme is superior to other sink location service schemes when supporting all communication modes.
