中文摘要

Energy conservation and network performance are critical issues in wireless
sensor networks (WSNs). This study presents a novel efficient communication
topology control protocol, called Quorum-based Load-Sharing Control Protocol
(QLSCP). QLSCP is a quorum-based communication protocol, which chooses
appropriate communication nodes, adjusts the service loads of critical nodes, and
performs adaptive sleep management. QLSCP is suitable for harsh environments
without a central control server calculating the locations of sensors, using the factor of the remaining power to build the system topology. The proposed protocol divides the
topology operation into topology formation, adjustment, and execution phases. The
topology formation phase builds the backbone of an enhance tree. In the topology
adjustment phase, the enhance tree is adjusted by an optimal balance of critical nodes
in the backbone. In the topology execution phase, the Efficient Surplus-energy
Consuming (ESC) mechanism is proposed to efficiently exhaust the energy of each
node. The ESC mechanism is designed to efficiently exhaust the latest remaining
electronic power of sensor nodes. Simulation results of QLSCP demonstrate that it efficiently achieves to prolong system lifetime in harsh environments.
