“…AHDR is a proactive mesh routing protocol described in [6] and [7] which operates at layer three in the META-MANET implementation. As such, ARQ in layer two is not aware of the forwarded packets, and therefore each ARQ pair is managing a single hop: this flow exercises three separate ARQ transmitter/receiver pairs which are independently synchronized and managed.…”

“…With ARQ enabled, however, all of the offered data blocks can successfully reach the receiver. Under these circumstances, a perfect, omniscient ARQ implementation would follow the line indicated by the dashed line (6). In reality, the line tops off (7) due to extraneous retransmissions and a greater level of ARQ signaling overhead (b).…”

The use of automatic repeat-request (ARQ) over a mobile ad-hoc network (MANET) presents unique challenges in handling signaling, connection identification, and implementation. This paper describes the implementation of a selective-repeat ARQ protocol in a mesh MANET called Mesh-Enabled Tactical Adaptive -MANET (META-MANET). The mesh MAC operates over the 802.16d physical (PHY) layer. The implementation of this ARQ protocol follows the specification described in the IEEE 802.16 standard with unique adaptations for mesh operations. Our implementation preserves the opportunity for future interworking with standards-based devices to the greatest extent possible. We hypothesized that adding ARQ would improve throughput and reduce loss rates. We present the results of lab testing of radio implementations of the ARQ-enhanced META-MANET protocol in RFcabled with emulated loss and mobile outdoor wireless environments. This testing is analyzed for topologies of two nodes to eight nodes and the emulation of various dynamic mobile topologies across terrain and obstructions. The impact to application traffic packet loss rate, throughput, latency, and multi-hop throughput are analyzed and presented. Several controlled scenarios were performed, with and without ARQ, to compare the performance of our implementation. We found that the implementation of ARQ over the mesh yielded significantly improved throughput, as perceived by the application, under many conditions. Overall, this study demonstrates the feasibility of implementing a standardized ARQ mechanism over a mesh topology in high-bandwidth environments with multiple nodes in a moving topology.

“…We base our analysis on the abstraction and generalization of AHDR -a hierarchical routing and adaptive network topology maintenance framework [3] [4]. On a high level, AHDR implements a strategic hybrid combination of proactive and reactive schemes, which provides updated route information for neighbor nodes, and offers optimized route resolution for unknown routes in a fast changing topology.…”

In this paper, we provide a parametric model for analyzing the control overhead usage in mobile ad-hoc networks (MANET). In particular, we focus on evaluating the impact of the hierarchy of both topology formation and routing on the scalability of overhead usage. Via an analytical approach, we quantitatively characterize the amount of overhead under different domain sizes, as well as other design parameters. The results help us to assess optimal scaling of overhead traffic as a function of network size N and to provide insights into developing scalable routing architectures for MANET.
