A Mobile Ad hoc Network (MANET) is a collection of mobile nodes that operate
without any backbone infrastructure support. Implementation of MANETS is very useful
in certain military applications and during emergency situations such as earth quakes
and re accidents. In MANETS, routing decisions are governed by the operating routing
protocol. Mobility is one of the most important factors to be considered in developing such
routing protocols. The e ect of mobility on a network is quanti ed in terms of link and
route duration times. Therefore, understanding mobility and its e ect on path duration
will de nitely help in coming up with a better routing algorithm.
In this thesis, we discuss the importance of mobility and its impact on a network. Also,
we tried to come up with an enhanced version of the mathematical model for the path
duration estimate from an existing model. One application of the path duration estimate
is to select a route with maximum expiry time unlike most of the routing algorithms which
choose a path based on shortest path. First, we estimate route expiry time with a single
relay node between the source and the destination. With this simple scenario, we analyze
how long it takes for a relay node to come out of the transmission range of the source node.
Then, we generalize the analysis for h number of hops used to reach destination. Also,
the e ect on path duration due to parameters such as transmission range, node mobility,
relative velocity, and number of hops in the route is studied. Simulations are performed in
MATLAB and the signi cance of the proposed model is discussed with an analysis of the
results obtained. / Thesis (M.S.)--Wichita State University, College of Engineering, Dept. of Electrical Engineering and Computer Science
