“…One study recommended the usage of the Microwave band, specifically 902-928 MHz, in order to overcome the propagation problems and provide a greater channel bandwidth to support higher data rates. 37 The engineering challenge to this is that it requires a radio that can simultaneously operate in the VHF band for backwards compatibility and operate in the microwave band to achieve the higher data rates required for the Army After If a protocol like JITTER is implemented as part of the threshold JTRS the system will be better able to meet the dynamic reconfiguration requirements, though changes to the JTA-A will have to be made to accommodate the newer protocols.…”

“…Several unicast ad hoc routing protocols have been proposed. They include: JACS 5, ABR 6, 7, 8, ZRP 1, AODV 2, etc. While most of these protocols are based on conventional routing metrics (delay, throughput, minimum‐hop), ABR employs a new routing metric known as ‘ associativity ’ or ‘ longevity ’ of a route.…”

Mobile ad hoc networks are recognized by their abilities to form, sustain, and deform networks on-the-fly without the need for any pre-established and fixed infrastructures. This wireless multi-hop technology requires adaptive networking protocols with low control overhead and low power consumption to operate efficiently. Existing research so far are mainly concerned with unicast routing for ad hoc mobile networks. There is a growing interest in supporting multicast communication in an ad hoc mobile environment. In this paper, the associativity-based ad hoc multicast (ABAM) routing protocol is proposed. The concept of association stability is utilized during multicast tree discovery, selection, and reconfiguration. This allows routes that are long-lived to be selected, thereby reducing the frequency of route reconstructions. ABAM employs a localized route reconstruction strategy in response to migrations by source, receiver, and tree nodes. It can repair an affected subtree via a single route reconstruction operation. ABAM is robust since the repair can be triggered by a node in the tree or by the migrated node itself. ABAM is also capable of handling multicast group dynamics when mobile hosts decide to join and leave an existing multicast group. Our simulation results reveal that under different mobility scenarios and multicast group size, ABAM has low communication overhead and yields better throughput performance.
