Abstract
Future wireless networks like mobile ad hoc networks and wireless mesh networks are expected to play important role in demanding communications such as mission critical communications. MANETs are ideal for emergency cases where the communication infrastructure has been completely destroyed and there is a need for quick set up of communications among the rescue/emergency workers. In such emergency scenarios wireless mesh networks may be employed in a later phase for providing advanced communications and services acting as a backbone network in the affected area. Internetworking of both types of future networks will provide a broad range of mission critical applications. While offering many advantages, such as flexibility, easy of deployment and low cost, MANETs and mesh networks face important security and resilience threats, especially for such demanding applications. We introduce a family of key agreement methods based on weak to strong authentication associated with several multiparty contributory key establishment methods. We examine the attributes of each key establishment method and how each method can be better applied in different scenarios. The proposed protocols support seamlessly both types of networks and consider system and application requirements such as efficient and secure internetworking, dynamicity of network topologies and support of thin clients.

An efficient networking solution for the support of the central disaster management entity would be the employment of adaptive, self-organized networks with advances networking capabilities, and redundant characteristics like wireless mesh
Summary
Consider a disaster situation, such as an earthquake, a flood, or a terrorist attack, where the commercial network infrastructure is destroyed or out of order. These teams gradually become part of coordinated action by a central disaster management entity, which requires more time to arrive at place, set up its infrastructure, and become operational Approaching this scenario from a networking perspective, a sufficient approach would be the support of the initial groups of rescue workers by communication devices with mobile ad hoc networking capabilities. Their nature and characteristics pose a number of nontrivial challenges to their security design, architecture, and services In both MANETs and wireless mesh networks, like in any other type of network, trust cannot be created among the network nodes without the existence of predefined prior known information available to all nodes beforehand. A MANET node can be considered as a mesh client and can perform seamless handovers between access points of the mesh network or between the MANET and the mesh network
