Dynamic Data Dissemination Technique for WSN

In wireless sensor networks, there is a need to have energy efficient data dissemination approaches at routing layer due to limited battery capacity of a sensor node. The article proposes an energy efficient virtual grid based data dissemination algorithm in wireless sensor networks. We consider a scenario having multiple sources and sinks. In order to perform the task of packet forwarding in an energy efficient manner, we consider the construction of a virtual grid based architecture. The idea is to divide the network into equally sized grids and each grid takes over the responsibility of data dissemination after periodic interval of time. We perform the simulation of the protocol in ns-2 and results show that this scheme performs better than the static grid based approaches.
