New Collision Avoidance Protocol in Real-Time Wireless Data Communication

摘要

A primary challenge in wireless real-time data communication network applications is how to carry out wireless data communication given source-to-sink, end-to-end deadlines when the communication resources are scarce. Although routing/data transport solutions have been proposed in the context of wireless ad hoc networks, the characteristics of wireless data communication networks make the problem different. In this paper, we develop New Avoiding Collision Protocol that offers significant advantages over existing wireless real-time data communication schemes. It reduces contentions to improve real-time performance by providing the flexibility of the nonlinear slack allocation. Collision Avoidance Protocol delays data packet transmission nonlinearly during forwarding for a duration that correlates with their remaining deadline and distance to the destination. Also we implement the The primary contribution of our work is more effective communication; and avoiding the contention in bursty traffic by using braided multi-path routing.
