“…An alternative approach of enforcing admission control is to calculate available bandwidth based on the effective link capacity and channel busy ratio [8]. However, with differentiated frame concatenation, it is quite difficult to know exactly how much bandwidth is achievable for flows of different categories.…”

Providing Quality of Service (QoS) to users in a wireless ad-hoc network is a key concern for service providers. With the availability of multiple rates in IEEE 802.11a/b/g wireless LANs, it is desirable to improve the network capacity and temporal fairness by sending multiple consecutive frames (also referred as frame concatenation mechanism in [14]) over high rate links, as proposed in opportunistic auto rate (OAR [10]). However, OAR does not consider the effect of frame sizes and may yield unsatisfactory performance for high priority multimedia flows transmitting over low rate links. Therefore, a more appropriate frame concatenation strategy and a corresponding service differentiation scheme should be devised to provide better performance for high priority voice/video flows than low priority data flows, under various channel rate scenarios. In this paper, we first analyze the effect of frame size on the performance of OAR. Then, we propose a general concatenation mechanism (GCM), a more accurate frame concatenation mechanism for multi-rate MAC with better fairness. Finally, we propose two mechanisms: adaptive weighted fair frame concatenation mechanism (AWFCM) and adaptive QoS aware frame concatenation mechanism (AQCM), for supporting service differentiation and QoS in multi-rate wireless ad hoc networks. The primary idea is to adjust the number of concatenated frames based on flow weights/priorities, frame sizes, link rates, and network traffic. Simulation results show that the proposed mechanisms achieve desirable performance on supporting multimedia applications in multi-rate wireless ad-hoc networks.

“…With multi‐rate medium access (MAC), the distance of a link may be much smaller due to transmission with high data rate, resulting in more intra‐flow interference. To consider both the mobility, multi‐rate feature, and the multi‐link interference, Li and Prabhakaran 12 proposed route available bandwidth (RAB) and route reliability (RR) metrics when admission control decision is made.…”

There has been increasing interest in deploying a team of robots, or robot swarms, to fulfill certain complicate tasks such as surveillance. Since robot swarms may move to areas of far distance, it is important to have a pervasive networking environment for communications among robots, administrators, and mobile users. In this paper, we first propose a pervasive architecture to integrate wireless mesh networks and robot swarm networks to build a robot swarm communication network within the areas of special interest. Under the proposed architecture, one or more robots can get connected with a nearby mesh router and access the remote server, while a self-organizing mobile ad hoc network is formed within each swarm for communications among the robots. We then address and analyze many important issues and challenges. Finally, we describe our work to enable this architecture through a scalable algorithm for autonomous swarm deployment and ROBOTRAK, a socket-based-swarm monitoring and control toolkit. Extensive simulation results and demonstrations are presented to show the desirable features of the proposed algorithm and toolkit.

Abstract-There have been increasing interests in deploying a team of robots, or robot swarms, to fulfill certain complicated tasks such as surveillance. Since robot swarms may move to areas of far distance, it is important to have a pervasive networking environment for communications among robots, administrators, and mobile users. For this purpose, we propose to build a wireless mesh network as the wireless backbone within the areas of special interest. One or more robots can get connected with a nearby mesh router and access the remote server. Within each swarm, a self-organizing mobile ad hoc network is formed. With this type of robot swarm communication network, there are many important open issues to be addressed.
