M. Tech. Electrical Engineering. / Wireless Sensor Networks (WSNs), which contribute to many applications in the military, environmental, medical, and civil domains, consist of small nodes with sensing, data computation, and wireless-communication capabilities. Node routing protocols have been specifically designed for WSNs in which energy conservation is an essential design issue. Rumor Routing (RR) is a hybrid protocol which combines both proactive and reactive routing methods, which balances event and query flooding quite well. This kind of protocol is well adapted to the case of few data and many queries. In this paper, Relative Coordinate Rumor Routing (RCRR), a straight-line routing method of both event and query, is proposed. It improves RR using some topological and abstract localisation method that shortens the source-to-sink route for the data transmission in order to save energy for broadcasting, even comparing to large data amount Routing Protocol. By adapting the Sensor-MAC protocol, the power consumption is much lower than that of the RR. Nodes can change to idle mode when notification of broadcasting does not apply to them. Simulation studies of RCRR with S-MAC can reduce energy by 60% compared to RR, which is a good improvement
