Wireless sensor networks consist of sinks, events, and a large number of tiny, multifunctional and battery-powered sensor nodes. Thousands of the sensor nodes are randomly distributed over a vast field to self-organize a large-scale wireless sensor network. The sensor nodes monitor some events in surrounding environments, such as temperature, humidity, sound, vibration, presence of objects, and so on. In wireless sensor networks, data dissemination to multiple mobile sinks consumes a lot of energy. Various grid-based data dissemination schemes have been proposed over the years to reduce the energy consumption in wireless sensor networks. Energy is one of the most important aspects for designing a data dissemination protocol for the applications such as battle-field monitoring, habitat monitoring, etc.
