Plenary Abstracts

Wireless Mesh Networks (WMNs) have revolutionized the provisioning of broadband wireless Internet service to a community of users. A group of static mesh router automatically interconnect themselves to form a Web of connection and employ multi-hop forwarding to connect to the Internet Gateway (IGW). Thus, we see that is critical to establish and ensure a collaborative framework at the MRs. All existing mesh routing protocols assume that each MR honestly participates in packet forwarding. But, this is valid only in a network managed by a single trusted authority such as University or Enterprise. Typically, mesh routers can be operated by different operators. Thus, a malicious user can erect a selfish MR that prioritizes treatment for the traffic originating from its mesh clients and drop´s others traffic. This results in degradation of network performance. We discuss various existing schemes with respect to detect selfishness in WMNs, and highlight their relative advantages and deficiencies.
