Efficient Broadcasting In Mobile Ad-Hoc Networks Abstract

Introduction to Efficient Broadcasting In Mobile Ad-Hoc Networks Mini Project:

MANETs is an self-configuring infrastructure less network in mobile devices connected by wireless. The main objective of Efficient Broadcasting In Mobile Ad-Hoc Networks Mini project is to determine a small set of forward nodes to ensure full coverage.

The use of laptops (802.11/Wi-Fi) and other wireless devices needs an efficient broadcasting with guaranteed coverage, which is successfully met by this project.

A framework is used to model inaccurate local views in MANETs, where full coverage is guaranteed if three sufficient conditions, connectivity, link availability, and consistency, are met.

 Mobile ad-hoc network is an autonomous system of mobile nodes connected by wireless links Nodes in mobile ad-hoc network are free to move and organize themselves.  The path between each pair of the users may have multiple links and the radio between them can be heterogeneous. The popular IEEE 802.11 “WI-FI” protocol is capable of providing ad-hoc network facilities at low level, when no access point is available. However in this case, the nodes are limited to send and receive information but do not route anything across the network. Mobile ad-hoc networks can operate in a standalone fashion or could possibly be connected to a larger network such as the Internet. Mobile ad-hoc networks can turn the dream of getting connected “anywhere and at any time” into reality. Typical application examples include a disaster recovery or a military operation. This project works on different routing algorithm for getting full coverage and efficient use of this network.

Three solutions are proposed to satisfy those conditions. An minimal transmission range that maintains the connectivity of the virtual network constructed from local views. Then, two transmission ranges, one for neighborhood information collection and the other for actual data transmission, to form a buffer zone that guarantees the availability of logical links in the physical network. Finally, a mechanism called aggregated local view to ensure consistent local views.
