Tactical Wireless Communications and Networks: Design Concepts and Challenges

11.4 Conflict Resolution for Shared Resources

This section presents an approach for resolving conflicts between two NMs where one owns a specific set of resources meant to be shared with another peer network. A known case is the resource management of NCW channels (explained in Chapter 6), which is part of WIN-T and is managed by the WIN-T network manager, but shared with the Joint Tactical Radio System (JTRS) WNW. The JTRS WNW NM (known as JWNM) can optimize the WNW network throughput more efficiently if it can influence how NCW channels are allocated. Specifically, which nodes with both (WNW and NCW) capabilities can use NCW channels, and at what times, in order to optimize the WNW subnet throughput efficiency? The presented approach, while illustrated for the NCW case, can easily be adapted for other shared resources.

11.4.1 Tactical Network Hierarchy

Please refer back to Figure 6.1, which shows the US arm tactical GIG network deployment with the hierarchy of waveforms (SRW—Soldier Radio Waveform, WNW, HNW—Highband Networking Waveform, and NCW). NCW reach-back capabilities are used at the WNW local subnets level, with each WNW subnet having some WNW/NCW-capable platforms for reach-back. JWNM plays a major role in managing the WNW local and global subnets. The Brigade Combat Team Modernization (BCTM) program utilizes the concept of a Manager of Mangers (MoM) to manage everything between the tactical GIG lower hierarchies, presented in Figure 6.1, all the way up to the WNW global ...
