A wireless sensor networks (WSN) comprises of a large number of sensor nodes and a few sink nodes. When multiple sink nodes are interested in collecting the readings of the same monitoring region, itpsilas conducive to exploit the sharing route in order to save bandwidth and power consumption and prolong WSNpsilas lifetime. This paper proposes a dynamic route sharing protocol (DRSP) which constructs sharing routes based upon different attributes (for example, frequency, packet length or delay time) of the commands requested from different sink nodes. The proposed DRSP dynamically adjusts data transmission route to achieve the goals of routes sharing and route length reduction. Simulation study shows that DRSP saves more energy and bandwidth consumptions than the existing work and thus prolongs the WSNpsilas lifetime.
