Existing routing protocols for wireless ad hoc networks assume a homogeneous network with either omnidirectional antennas or smart (beamforming) antennas. However it is possible to have a heterogeneous network with each node either using an omnidirectional antenna or a smart antenna. We investigate the routing and MAC layer issues that arise in such(More)
We propose a viral address assignment scheme for wireless ad hoc networks. In this scheme, a node has multiple addresses and each address of the node corresponds to a logical location of the node in the network. Further, addresses are allocated in a contagious fashion to mimic a viral growth. We study some of the issues in such a scheme
Transport control protocol (TCP) is the most widely used transport protocol in the Internet. However, there are several performance issues related to TCP when used in wireless ad hoc networks. We compare the performance of TCP flows with directional and omni-directional antennas. We find that directional antennas improve TCP throughput up to 115% and reduce(More)
