A Cross Layer Protocol for Optimal Performance of Software Defined Radios in Mission Critical Networks
Irum Nosheen, Shoab Ahmed Khan · 2017
Unlike conventional mobile ad hoc networks, tactical networks which provide communication of software defined radios (SDRs) in mission critical and time sensitive applications require cognitive functions across the TCP/IP stack to encounter strict constraints while providing smooth incorporation with IP based applications. Tactical applications are mission critical and thus pose unique requirements for the network, including decentralized control and mission specific latency bounds for end-to-end data delivery. The paper presents a cross-layer design, which utilizes interactions among layers to achieve optimal performance in terms of energy efficiency, reliable packet delivery at appropriate data rate and within affordable latency bounds in multi-hop tactical networks. The proposed design is tested in a number of scenarios to demonstrate enhanced performance in critical network configurations where SDRs effectively adapt to the dynamic environment.
