“…We implemented our GES-MAC as well as previous protocols, namely, LASMAC [3], [4], SMAC [1], BMAC [10], and COR [17] using Tip30 nodes and using NS-2 version 2.33 for performance comparison. Except COR which does not use duty cycling, all other implemented protocols have duty cycle, but the ratio is different.…”

“…LASMAC [3], [4], RMAC [5], and DW-MAC [12] are energy efficient as well as achieve relatively higher goodput by node scheduling in a multi-hop environment. Unlike SMAC, the listen period is used to schedule nodes in a routing path (i.e., deciding when to wake up, send, or receive) and data packets are forwarded in the sleep period along with the scheduled nodes.…”

SUMMARYIn the sensor networks for surveillance, the requirements of providing energy efficiency and service differentiation, which is to deliver high-priority packets preferentially, while maintaining high goodput, which is to deliver many packets within their deadline are increasing. However, previous works have difficulties in satisfying the requirements simultaneously. Thus, we propose GES-MAC, which satisfies the requirements simultaneously. GES-MAC reduces idle listening energy consumption by using a duty cycle, periodic listen (i.e., turn on radio module) and sleep (i.e. turn off radio module) of sensor nodes. Cluster-based multi-hop scheduling provides high goodput in a duty-cycled environment by scheduling clusters of nodes in the listen period and opportunistically forwarding data packets in the sleep period. Priority-aware schedule switching makes more highpriority packets reach the sink node by letting high-priority packets preempt the schedules of low-priority packets. In experiments with MICA2 based sensor nodes and in simulations, the energy consumption of the radio module is reduced by 70% compared to the approaches without a duty cycle, while providing 80% ∼ 100% goodput of the approaches that provide high goodput. Service differentiation is also supported with little overhead.
