Disasters are of varying intensity and occurrence ranging from less frequent like earthquake, volcanic eruption to more frequent like floods, fire, drought, cyclones, landslides besides industrial reaction and epidemics. Disasters kill at least one million people each decade and leave millions more homeless (ITU, TDBEC).
When disaster strikes, communication link are often disrupted, yet for disaster relief workers, these links are essential in order to answer critical questions as to how many people have been injured or died, where the injured are located and the extent of the medical help needed. In disaster and emergency situations, communications can save lives.

The collapse of communications infrastructure, due to the collapse of antennas, buildings, power etc is the usual effect of disaster. The breakdown of essential communications is one of the most widely shared characteristics of all disasters. Whether partial or complete, the failure of communications infrastructure leads to preventable loss of life and damage to property, by causing delays and errors in emergency response and disaster relief efforts (Townsend and Moss, 2005).
Yet despite the increasing reliability and resiliency of modern communications networks to physical damage, the risk associated with communications failures remains serious because of growing dependence upon these tools in emergency operations. One solution to this problem is the use of wireless communication systems.
In wireless networking, there are two main architectures: infrastructure networks and mobile ad hoc networks (MANETs). Infrastructure networks include cellular networks and wireless local area networks. Users are connected via base stations/access points and backbone networks. Although users can handover between base stations or access points and roam among different networks, their mobility is limited within the coverage areas of the base stations or access points. This is illustrated in
figure 1. Ad hoc networks on the other hand, exclude the use of a wired infrastructure. Mobile nodes can form arbitrary networks “on the fly” to exchange information without the need of pre-existing network infrastructure. Ad hoc networks can extend communication beyond the limit of infrastructurebased networks.
A mobile ad hoc network (MANET) is defined by the Internet Engineering Task Force (IEFT) as an autonomous system of mobile nodes connected by wireless links in which each node operates as an end system and a router for all other nodes in the network (IETF, MANET). It is a collection of wireless mobile nodes which dynamically form a temporary network without the aid of any established infrastructure or centralized administration. These characteristics make MANET suitable for mission-critical applications, such as disaster recovery, crowd control, search and rescue and automated battlefield communications.
