Sleep thrashing and its prevention in ad hoc networks

In the disaster-hit area, communication supporting systems using the existing mobile ad hoc network technique could not function as expected and communication would be interrupted from time to time, since they have not taken into consideration the issue of sleep, which is a very frequently used means for users to save their battery consumption. Especially, a phenomenon called sleep thrashing may occur, which would collapse a mobile ad hoc network. This paper explains the concept of sleep thrashing, and proposes a system model and a CDS-based solution for reducing its negative effect on communication. Simulation experiments have been conducted to demonstrate the effectiveness of the proposed approach.
