Abstract

In wireless networks, a watchdog mechanism can be a part of the security architecture used to identify nodes that fail to forward the packets they agree to forward. In this paper, we propose two protocols to address the ambiguous collision limitation of watchdogs. The Watchdog Alert (WA) and Watchdog Confirmation (WC) protocols are variants of the Carrier Sense Multiple Access with Collision Avoidance Protocol (CSMA/CA). We analyse the trade-offs between throughput and watchdog success probability of each protocol, comparing it to CSMA/CA.
