Abstract

This paper presents a master/slave cluster based mobile ad-hoc network architecture designed for multihop multimedia communications. The proposed architecture is a mixture of two different types of networks: managed (master-and-slave) and ad-hoc. In this architecture, the participating slave nodes (SNs) of each cluster communicate with each other via their respective Master Nodes (MNs) in a managed network. Communications between the clusters is performed via their MNs which operate in an ad-hoc mode. For network implementation, an IEEE 802.11 Wireless LAN (WLAN) has been deployed. Since there is no stationary node in this network, all the nodes in a cluster may have to move together as a group. However, in order to allow a mobile node to move to another cluster, which requires changing its point of attachment, a handoff process utilizing mobile IP version 6 (Ipv6) has been considered. For ad-hoc routing between the master nodes (i.e., Ms), the Ad-hoc On-demand Distance Vector (AODV) protocol has been deployed. In assessing the network performance, field test trials have been carried out to measure the proposed network performance. These measurements include packet loss, delays under various test conditions such as a change of ad-hoc route, handoffs, etc.
