Abstract:

Sensor networks provide sensing capability in a wide range of application domains such as healthcare, home, military, commercial and so on. Typically, energy is much more limited in sensor networks than in other wireless networks. This is due to the intrinsic nature of sensing devices and the difficulty in recharging their batteries. The nodes in the network usually dissipate energy by transmitting redundant packets. Additionally, in multi-event scenarios, the nodes fill up their caches with various events, instead of a specific set of the events, decreasing the in-network data aggregation efficiency. In this paper, we propose Reactive Event Flow Shaping (REFS), an energy-efficient data dissemination protocol for wireless sensor networks. REFS selectively prunes links and narrows the event flows according to the heuristics described. From our simulation, we have observed that 40\% savings is achieved in terms of the number of transmissions and cache performance compared to flooding.
