Route Stability in MANETs under the Random Direction Mobility Model

Route Stability in MANETs under the Random Direction Mobility Model

Abstract:


A fundamental issue arising in mobile ad hoc networks (MANETs) is the selection of the optimal path between any two nodes. A method that has been advocated to improve routing efficiency is to select the most stable path so as to reduce the latency and the overhead due to route reconstruction. In this work, we study both the availability and the duration probability of a routing path that is subject to link failures caused by node mobility. In particular, we focus on the case where the network nodes move according to the Random Direction model, and we derive both exact and approximate (but simple) expressions of these probabilities. Through our results, we study the problem of selecting an optimal route in terms of path availability. Finally, we propose an approach to improve the efficiency of reactive Routing protocols.

Algorithm / Technique used:

Random Direction model.






Algorithm Description:

The Random waypoint model is a random-based mobility model used in mobility management schemes for mobile communication systems. The mobility model is designed to describe the movement pattern of mobile users, and how their location, velocity and acceleration change over time. Mobility models are used for simulation purposes when new network protocols are evaluated.

In random-based mobility simulation models, the mobile nodes move randomly and freely without restrictions. To be more specific, the destination, speed and direction are all chosen randomly and independently of other nodes.

Existing System:

The problem of link and route stability has been widely addressed in the literature. Routing protocols accounting for route stability while selecting the source-destination path can be found , just to name a few. In particular, the work in considers nodes moving along nonrandom patterns and exploits some knowledge of the nodes motion to predict the path duration. Studies on link and path availability and duration are presented. A partially deterministic and a Brownian motion, where nodes start moving from the same location, are considered.
Proposed System:

We focus on the stability of a routing path, which is subject to link failures caused by node mobility. We define the path duration as the time interval from when the route is established until one of the links along the route becomes unavailable, while we say that a path is available at a given time instant t when all links along the path are active at time t. Then, our objective is to derive the probability of path duration till time t and the probability of path availability at time t.

Abstract—

A fundamental issue arising in mobile ad hoc networks (MANETs) is the selection of the optimal path between any two
nodes. A method that has been advocated to improve routing efficiency is to select the most stable path so as to reduce the latency
and the overhead due to route reconstruction. In this work, we study both the availability and the duration probability of a routing path
that is subject to link failures caused by node mobility. In particular, we focus on the case where the network nodes move according to
the Random Direction model, and we derive both exact and approximate (but simple) expressions of these probabilities. Through our
results, we study the problem of selecting an optimal route in terms of path availability. Finally, we propose an approach to improve the
efficiency of reactive routing protocols.
