| Abstract | Although Wireless Mesh Network (WMN) has many similarities with ad hoc networks, the existing ad hoc routing protocols cannot be used efficiently because they don't scale well as the network size increases beyond few hundred nodes. The main reason behind the lack of scalability is that most of the existing protocols rely on flat and static addressing in which we have to keep track of each node individually. Dynamic address allocation can solve the problem of scalability. "Party" is one of such recently proposed routing protocols, but it does not have efficient mechanism for dynamic allocation of address in the case of node failures and node movements. In this thesis, an efficient mechanism is proposed to incorporate in Party protocol to enhance it for dynamic address allocation in the case of node failures and node movements. This new proposed protocol is named as Enhanced Mobile Party (EMP). EMP provides better scalability as network size increases and as number of traffic flow increases, so is better suited for WMNs. With the help of network level simulation, the performance of proposed EMP is extensively evaluated and compared to existing routing protocols AODV (reactive one) and DSDV (proactive one). It is observed that proposed EMP outperforms the AODV and DSDV in terms of signaling overhead as the network size and the number of traffic flow increases. In terms of packet delivery ratio, EMP performs better in static case and in case of mobility it provides PDR of more than 96.5%. Furthermore addition of two mechanisms- one to make EMP node communicate with external node and another to allow roaming of non-EMP node in proposed EMP network, make the proposed new protocol EMP more flexible and adaptable compared to existing routing protocols. But the cost paid in the proposed EMP is increased end-to-end delay |
