.11 in several ways: energy conservation and self-configuration are primary goals, while per-node fairness and latency are less important. S-MAC uses a few novel techniques to reduce energy consumption and support self-configuration. It enables low-duty-cycle operation in a multihop network. Nodes form virtual

Fair Scheduling in Wireless Packet Networks

by Songwu Lu, Vaduvur Bharghavan, Rayadurgam Srikant - IEEE/ACM Transactions on Networking , 1997
"... Fair scheduling of delay and rate-sensitive packet flows over a wireless channel is not addressed effectively by most contemporary wireline fair scheduling algorithms because of two unique characteristics of wireless media: (a) bursty channel errors, and (b) location-dependent channel capacity and e ..."

Routing In Clustered Multihop, Mobile Wireless Networks With Fading Channel

by Ching-chuan Chiang, Hsiao-kuang Wu, Winston Liu, Mario Gerla , 2005
"... A clusterhead-token infrastructure for multihop, mobile wireless networks has been designed. Traditional routing algorithms in wireline networks are not feasible for mobile wireless environment due to the dynamic change in link connectivity. To gain better performance for clustered multihop, mobile ..."

wireless networks, routing must take into account radio channel access, code scheduling, and channel reservation. In this paper, we propose some heuristic routing schemes for clustered multihop, mobile wireless networks. A packet delay improvement up to fourfold has been observed in our simulations

Joint Channel Assignment and Routing for Throughput Optimization in Multi-radio Wireless Mesh Networks

by Mansoor Alicherry , Randeep Bhatia , Li Erran Li , 2005

Joint rate control and scheduling in multihop wireless networks

by Xiaojun Lin, Ness B. Shroff - IN PROCEEDINGS OF IEEE CONFERENCE ON DECISION AND CONTROL , 2004
"... We study the joint problem of allocating data rates and finding a stabilizing scheduling policy in a multihop wireless network. We propose a dual optimization based approach through which the rate control problem and the scheduling problem can be decomposed. We demonstrate via both analytical and n ..."

Scheduling algorithms for TDMA wireless multihop networks

by Petar Djukic , 2008
"... Current and future wireless standards use TDMA to provide guaranteed Quality-of-Service (QoS) in the network. While these standards specify how transmissions should occur, they do not discuss scheduling algorithms to find when transmissions should oc-cur (transmission schedules). Despite the technol ..."

the technological advances, the question of finding transmission schedules has existed for the past twenty years without a satisfactory an-swer. This thesis presents a new class of scheduling algorithms for Time Division Mul-tiple Access (TDMA) wireless multihop networks. These algorithms have three major

Z-MAC: a Hybrid MAC for Wireless Sensor Networks

by Ajit Warrier, Jeongki Min, Injong Rhee , 2005
"... Z-MAC is a hybrid MAC protocol for wireless sensor networks. It combines the strengths of TDMA and CSMA while offsetting their weaknesses.
