Mobile ad-hoc network data communication in large geographic areas

A mobile ad-hoc network (MANET) is a group of wireless, mobile, battery-powered clients and servers that autonomously form temporary networks. Three data communication modes can be provided in a MANET: data broadcast, data query, and peer-to-peer messaging. In support of data communication needs in these networks, a database is utilized for data broadcast and data query. This paper presents the TriM protocol (tri-modal communication) to handle data communication in a MANET. TriM accommodates node disconnection and reconnection through periodic synchronization while having minimum power consumption. This protocol has been shown capable of allowing all three data communication modes in a single network deployment in small geographic regions. This paper extends those results by evaluating TriM in the larger geographic regions present in the military scenario. Simulation shows that TriM is capable of providing power-aware and mobile-aware data communication services in the larger regions of the military scenario
