Mobile Ad Hoc is a self constructive network of mobile nodes connected by wireless link to form at arbitrary topology exclusive of existing infrastructure. MANET's network topology unpredictable and change quit frequently due to its dynamic nature. MANET's networks are similar to traditional networks however posses few challenges mainly due to mobility of communicating nodes. This essay report illustrates the investigation of different mobility models and challenges of mobile ad hoc networks faces during communication.

The Mobile Ad Hoc Network builds networks instinctively without the aid of infrastructure. The each node in the network acts as end node or intermediate node //due to decentralize nature of Mobile Ad Hoc Networks [1] [2]. However, with advent of wireless technology the use of mobile ad hoc networks increased, due to its robustness but the various major constraints such as limited battery charge, frequently change of topology and security issues makes its use susceptible.

In single entity mobility model each node moves independently in the network area whereas in group mobility model, nodes are believe to be in a group and the mobility of node is often reflective of the movement pattern of whole group. The distinctive feature of every mobility model is to guarantee that the mobile node will not travel outside the network boundary [3].

Random based Mobility Models

In this type of mobility models nodes move freely in the network area without any constraint. The speed and direction of nodes in random based mobility are chosen randomly.
