ABSTRACT

Wireless sensor networks are composed of many wireless sensor nodes and have many application ranges. The sensor nodes are resource constrained in memory space, CPU computation, and energy capacity. These constrains are restricted to extend the sensor networks to the more applications. In these networks, many energy efficient mechanisms are proposed with wakeup scheduling schemes that wake up the sleeping sensor nodes to be active states of the sensor nodes synchronously or asynchronously. This paper proposes the scheme of energy efficient and load balancing wakeup scheduling of sensor nodes by using cross layer approach with not disjointed multipath. Our proposed scheme constructs the graph of not disjointed multi-paths from source nodes to the sink node. This graph is maintained by each sensor nodes and is used in the wakeup scheduling of the sensor nodes synchronously. Our proposed scheme wakes up the sensor nodes along the not disjointed multipath from the sensor nodes in range of interests to the sink node synchronously. Our proposed scheme is analyzed to have many merits that are the low and expected packet latency, the energy efficiency, and the energy balancing of wireless sensor networks through the combined transfer of packets and the combined processing of packets.
