Abstract : Future Air Force networks will face the challenge of providing robust data and circuit services to tens or hundreds of fixed and mobile users with different service levels. Some of the service challenges include guaranteed rates, communication over difficult channels, hard time-deadlines, reliable message delivery over unreliable networks, security, and policy-driven resource allocation. In light of the propagation characteristics as well as the new challenges of the aerial layer communications, the project Cooperative Routing for Dynamic Aerial Layer Networks is funded by Air Force Research Laboratory (AFRL) under grant number FA8750-14-1-0077 to develop a novel and fundamental framework on which new enabling aerial layer communication technologies and protocols can be designed and analyzed. To be specific, the project 1) focuses on dynamic spectrum access (DSA) networks which efficiently allow different wireless nodes to co-exist in the same radio spectrum; 2) introduces a new cooperative aerial layer routing strategy based on mutual-information accumulation (e.g., rateless codes, fountain codes, and hybrid ARQ); 3) develops dynamic network resource management and collaborative routing strategies in support of joint aerial layer networking (JALN) concept; and 4) demonstrates the effectiveness of the strategies introduced using Ettus universal software radio peripheral (USRP) N210s. Our analytical results show that both the centralized and distributed algorithms can reduce up to 77% of the end-to-end delay compared to the traditional routing strategies in DSA networks; demo results using USRP N210s confirm analytical findings.
