Collaborative neighbour monitoring in TV white space networks

Abstract

Collaborative sensing among secondary users in television white space (cognitive radio) networks can considerably increase the probability of detecting primary or secondary users. In current collaborative sensing schemes, all collaborative secondary users are assumed to be honest; however, the deployment of such networks is susceptible to attacks by malicious users, in which malicious secondary users either report false detection results or inject falsified data in order to unduly occupy a specific channel and deny other nodes from using it. This work seeks to allow each secondary user to monitor its neighbour to ensure there is no spectrum abuse by any secondary users so as to improve spectrum fairness in dynamic spectrum access (DSA) networks.
