This paper considers the problem of self-diagnosis of wireless mesh networks (WMNs) and mobile ad-hoc networks (MANETs) using the comparison approach. In this approach, the network consists of a collection of n independent heterogeneous mobile or stationary hosts interconnected via wireless links, and it is assumed that at most sigma of these hosts are faulty. In order to diagnose the state of the wireless mesh and ad-hoc network, tasks are assigned to pairs of hosts and the outcomes of these tasks are compared. The agreements and disagreements among hosts are the basis for identifying the faulty ones. We develop a new distributed self-diagnosis protocol, called adaptive-DSDP, for MANETs and WMNs that identifies both hard and soft faults in a finite amount of time. We analyze the time and communication complexities of our protocol and compare it to existing self-diagnosis protocols
