Design and Performance Evaluation of Meghadoot - A Hybrid Wireless Network Architecture

This paper presents the design and evaluation of Meghadoot - a hybrid wireless network architecture that provides improved services, such as better connectivity among the users, efficient routing, and access to the Internet. Meghadoot architecture combines the advantages of both single-hop and multi-hop wireless networks. Meghadoot is extremely useful (a) as an alternative to existing wired or wireless last mile solutions, (b) to establish a network in a residential complex or in a university campus. The Meghadoot architecture has been implemented and tested in both the NS2 simulator and in the Linux kernel. Both, experimental and simulation results show an improved performance for Meghadoot, in terms of reduction in control overhead and increase in throughput over that of the existing approaches
