Data Dissemination in Wireless Sensor Network

A large sensing and monitoring task spread over vast geographical region can now be accomplished by deploying large number of tiny low cost wireless sensor nodes which self-organize themselves to form a sensing network, known as wireless sensor network. Wireless sensor network consist of event sink and large number of sensor node. The sensor nodes are low cost, low power and multi functional devices. Sensor node are randomly distributed over a vast field to self organize a large scale sensor network. Data dissemination in wireless sensor network consumes lot of energy, various protocols or scheme has been proposed over decades to reduce the energy consumption of wireless sensor network. Various schemes are helpful to reduce the energy consumption of wireless sensor network by creating the virtual grid. Grid is constructed only when if there is no valid grid is present in sensor filed and if valid grid is present then be use the exiting grid which reduce the energy consumption of sensor node to create grid again and again if event is occurred. We follow the diagonal path in our scheme to send the query or data from sink to source or vice versa which reduce the energy consumption of data dissemination in wireless sensor network.
