Cross Layer Adaptation of Check intervals in low power listening MAC protocols for lifetime improvement in Wireless Sensor Networks.

Escolar S, Chessa S, Carretero J, Marinescu MC - Sensors (Basel) (2012)

Bottom Line: We propose Cross Layer Adaptation of Check intervals (CLAC), a novel protocol intended to reduce the energy consumption of the nodes without significantly increasing the delay.CLAC uses routing and MAC layer information to compute a delay that matches the packet arrival time.The simulation results confirm that CLAC improves the network lifetime at no additional packet loss and without affecting the end-to-end delay.

ABSTRACT
Preamble sampling-based MAC protocols designed for Wireless Sensor Networks (WSN) are aimed at prolonging the lifetime of the nodes by scheduling their times of activity. This scheduling exploits node synchronization to find the right trade-off between energy consumption and delay. In this paper we consider the problem of node synchronization in preamble sampling protocols. We propose Cross Layer Adaptation of Check intervals (CLAC), a novel protocol intended to reduce the energy consumption of the nodes without significantly increasing the delay. Our protocol modifies the scheduling of the nodes based on estimating the delay experienced by a packet that travels along a multi-hop path. CLAC uses routing and MAC layer information to compute a delay that matches the packet arrival time. We have implemented CLAC on top of well-known routing and MAC protocols for WSN, and we have evaluated our implementation using the Avrora simulator. The simulation results confirm that CLAC improves the network lifetime at no additional packet loss and without affecting the end-to-end delay.

On the left, the routing protocol selects the path to connect two remote nodes i1 and i5 through the nodes i2, i3, and i4. On the right, nodes experience communication delays which are propagated down along the path from the source to the destination node.

Mentions: Figure 3 shows, on the left hand side, a simple scenario where i1 sends data to a remote receiver i5.The arrows show the path between the two nodes as computed by CTP. The right hand side shows the delays incurred as data propagates from i1 to i5, and how these are accumulated during the multi-hop transmission.
