“…In the other hand, and as it was presented above, the original 802.11b based DCF access mechanism uses a single First-In-First-Out (FIFO) queue used in best-effort manner. In this paper, we present a multipleclass queuing system using an adaptive Weighted Round Robin (WRR) scheme, which takes into account battery life and load of high priority traffic to provide service differentiation [13].…”

Today, the original IEEE 802.11 standard has several problems in providing Quality of Service in MANETs. A single FIFO queue is used in best effort manner and it does not support QoS. The upcoming IEEE 802.11e was drafted to overcome these drawbacks. In this paper we describe a new multiple queuing system with an adaptive scheduling taking into account the states of buffers and energy consumption in a mobile ad hoc network. The proposed scheduling scheme uses dynamic weights for each queue. We study the performance of this scheme and compare it with the original IEEE 802.11b and the upcoming IEEE 802.11e. We show through simulations that the proposedbuffer and energy based scheduling scheme improves overall end-to-end throughput, and gives better results than the original 802.11b and the Enhanced Distributed Coordination Function (EDCF), in terms of delay and total received and lost packets, as well as support service differentiation over multi-hop ad hoc networks.

Mobile Ad Hoc Networks in road transport applications exhibit special characteristics, mainly due to their dynamic chain behaviour. In this paper, we introduce a node decision algorithm in both the routing and packet priority mechanism, based on the node's driving direction with respect to the next hope towards packet destination. In the routing algorithm, a Router Direction Index (RDI) parameter is introduced to enhance the performance of AODV in updating its routing table, as well as to assist the destination nodes to choose route requests from different paths in inter-vehicular ad hoc network scenarios. A packet transmission priority is set according to the driving direction of both transmitter and receiver of the packet. Simulation results of the proposed algorithm for 200 vehicles travelling at speeds between 60 ~ 120 km/h on a 2-directional highway demonstrate a performance increase in the packet delivery ratio, and decrease in the packet end to end delay and routing overhead for the proposed algorithm.

In the IEEE 802.11 power saving mode (PSM) which is specified for distributed coordinate function (DCF), time is divided into beacon intervals. Beacon interval is composed of ATIM window and data transmit duration. When data transmission is needed, hosts must send and receive ATIM window frames during ATIM window. According to ATIM frames, each host decides to sleep or awake. Clearly, this method is not optimized one since it can't manage dynamic transmitting situation. To solve this problem, dynamic power saving mechanism (DPSM) is proposed. But in this method changing ATIM window size is linearly progressed and considering situation is highly limited. So we have developed new dynamic traffic assignment (DTA) systems for optimizing PSM in wireless networks. For this purpose, we bring in optimal state estimation which is formalized by mathematical equations that utilize a proven error calculation method, Kalman Filter. This method makes it possible to predict the best suitable ATIM window size to increase possible doze time. And it also improves power efficiency of wireless devices more than the one achieved through DPSM. In this way, we have developed basic mathematical system modeling in wireless networks and the usage of Kalman Filter. Simulation results show that proposed approach outperforms previous mechanisms PSM, DPSM in terms of throughput and the amount of energy consumed.
