Abstract:In wireless networks, devices can be equipped with multiple interfaces to utilize multiple channels and increase the aggregated network throughput. In fact, as the current price of network interface cards has fallen dramatically, applications have started to use multiple non-overlapping channels to get an enhanced bandwidth, with traditional standards such as IEEE 802.11 a/b/g. In this regard, a wireless network node equipped with more than one interface can concurrently communicate with other nodes on different channels. This operation results in less interference and collisions in the network, and therefore a better use of the network capabilities in terms of bandwidth. In this paper we propose an algorithm that uses multiple channels to improve performance in the counting of objects (people, animals, devices, vehicles, etc) based on wireless communications where devices are equipped with multiple interfaces, which works either for stationary nodes or in scenarios where nodes are moving even at high speeds. In particular, the technique of interface switching is used to take advantage of all the channels, even when the number of available interfaces is smaller than the number of channels. To validate and evaluate the performance and accuracy of the proposal, the algorithm is simulated using a famous network simulation tool called OMNeT++/INET. The results of the simulations show that the proposed algorithm efficiently exploits the advantages of multi-channel, by computing a number of nodes very close to the real one (even in the case of scenarios with nodes moving at high speeds) with an acceptable response time and total number of control messages sent by the nodes to accomplish the counting task.

Abstract:Recently, providing live video streaming over hybrid wireless mesh networks (WMNs) has been of great interest. In this kind of network, most of the users usually move with low speed and always keep their connections within the network by attaching to different mesh routers (MRs). When evaluating a mesh technology, it is important to pay special attention to this kind of device as it is mostly handled by the final user. These devices, known as STA nodes, neither run a routing protocol nor perform forwarding operations. Although our proposed distributed locator service in GREENIE makes hybrid WMNs more efficient for supporting STA nodes, video distortion increases when the number of them sharply augments. In order to address this problem, we equip MRs with an efficient multiinterface multichannel (MIMC) algorithm. The proposed algorithm is an engineering solution that completely considers the channel status and its queue length. Moreover, it is cost effective and simple in its implementation without imposing unnecessary complexity on the network. Simulation results using OMNET++ show that all the tested routing protocols, and GREENIE in particular, efficiently exploit the advantages of the designed MIMC algorithm by improving the video distortion, total capacity of successfully received video packets, number of successfully received video frames, packet delay variation, and end-to-end delay metrics. As a result, better video quality can be provided on STA nodes.

“…ETT, WCETT, and some others are all the routing metrics based on ETX. From the results of tests with variety of routing metrics in [ 12 ], the metric of hop count reflects the actual topology state better and achieves better performance ad hoc, while, for WMN which has relatively fixed nodes, ETX performs better.…”

“…This kind of method according to the expected transmission count (including retransmission count) considers the influence of packet loss rate and asymmetry of link in wireless network. Mogaibel et al experimentally verified ETX's high-speed transmission rate, and the performance was improved most especially on single-channel WMN in [ 12 ].…”

WMN (wireless mesh network) is a useful wireless multihop network with tremendous research value. The routing strategy decides the performance of network and the quality of transmission. A good routing algorithm will use the whole bandwidth of network and assure the quality of service of traffic. Since the routing metric ETX (expected transmission count) does not assure good quality of wireless links, to improve the routing performance, an opportunistic routing mechanism combined with long-term and short-term metrics for WMN based on OLSR (optimized link state routing) and ETX is proposed in this paper. This mechanism always chooses the highest throughput links to improve the performance of routing over WMN and then reduces the energy consumption of mesh routers. The simulations and analyses show that the opportunistic routing mechanism is better than the mechanism with the metric of ETX.
