Abstract
A mobile ad-hoc network (MANET) can be defined as a collection of autonomous nodes that can achieve wireless communication with each other without any centralise administration. Quality of service (QoS) and efficient routing protocol are the mechanisms which support the multimedia applications of the network. Recent technologies have intergraded wireless communication and Internet services in order to expand the traditional Internet applications. This thesis investigates a novel approach on MANETs, which support Internet services and can be used to establish an Internet connection between the network’s nodes.This thesis introduces a new concept of Internet-connected MANET routing protocol based on optimised link state routing algorithm. Backbone Internet-Connected – Optimised Link State Routing (BIC-OLSR) protocol is enhanced to provide QoS by utilising Internet connection and weighting algorithm in order to reduce end-to-end delay, increase the throughput and the packet fraction of the network. With detailed analysis, the research work investigates current routing protocols and technologies, which support Internet services.
BIC-OLSR is defined by the control messages, weighting algorithm and multipoint relay algorithm (MPR). The control messages identify the Internet connected nodes, the topology of the network and nodes neighbours. On the other hand, weighting algorithm based on control messages reveals the most efficient routing path based on the perspective of each node involved in the data transmission. MPR algorithm clusters the network and selects a Cluster Head based on the weighting algorithm. Simulations have shown that BIC-OLSR routing protocol provides QoS performance in different scenarios compared with OLSR routing protocol.
