Abstract

In this paper, we design a multi-interface model on single mobile node and every node in the cognitive network is implemented multiple transceivers. -persistent slotted CSMA is used as the access protocol. Interfaces with different channels may have different values of s. To avoid crosstalk, multiple transceivers of each node must work in the same state, only sending or receiving, at one time. This requirement limits the performance of -persistent algorithm. To solve this problem, we propose the Comprehensive -Persistent Algorithm (CPPA), which is to find an optical value of shared by one node’s multiple interfaces. Simulation experiments are conducted to evaluate the performance of our algorithm in terms of the throughput and the jitter. Results show that our algorithm performs better.
