Time synchronization is important for many applications running in wireless sensor network. A classical algorithm, Timing-Sync Protocol for Sensor Networks (TPSN), has been widely adopted, which can achieve of the goal of high accuracy and energy-efficiency. However, the accuracy of TPSN algorithm will decrease in practical environments since communication conflicts occur in an ad-hoc wireless environment...
A large number of ultra small satellites forming a wireless sensor network in space are able to be incorporated in space missions which are traditionally difficult for an individual satellite. Such a satellite-based communication network always needs higher energy efficiency to ensure a longer network lifetime. In this paper, a collaborative and self-organized algorithm is proposed to enhance energy...
Collaborative working manner of individual satellite nodes demand totally distributed algorithms and protocols. The mobile nature of these nodes requires that these algorithms and protocols must be adaptive to the ceaseless topology changes. This paper proposes an adaptive decision making function and weight factor in a highly efficient algorithm for the distributed nodes, which helps solving the...
