-Wireless Mesh Networks (WMNs) are the set of wireless nodes that can communicate with each other and forwarding each other’s packets. WMNs are multi-hop networks consisting of routers, gateways and mobile nodes, they aim at guarantee connectivity. They act as a key technology for next generation WMNs due to their low cost and relative ease of deployment they are an attractive paradigm and are advantageous to other wireless networks. WMNs build a multi-hop wireless backbone to interconnect isolated Local Area Networks and to extend backhaul access to users not within range of typical access points. This paper analysed routing protocol such as Ad hoc on Demand Distance Vector (AODV), Dynamic Source Routing (DSR), GRP -Geographic routing protocol, Temporary Ordered Routing Algorithm (TORA), and Optimized Link State Routing (OLSR) used in WMN where AODV and DSR are reactive routing protocol, OLSR and GRP are proactive routing protocol and TORA is a hybrid routing protocol. The routing protocol have been analysed with the performance metrics of throughput and delay under the simulation of ftp traffic and database traffic. With OPNET simulator, the results shows that in terms of ftp traffic load, TORA has very long delay. For throughput, OLSR outperforms the other routing protocols. Under database traffic load, OLSR has long delay and for throughput, DSR and TORA have high throughput. Keywords--AODV Ad hoc on distance vector; DSR Dynamic source routing; FTP File Transfer Protocol; GRP Geographic routing protocol; WMNs -Wireless Mesh Networks

In this paper an ANN model is developed to forecast the monthly inflation of Bangladesh as a function of its own previous value. The model selects a feed-forward backpropagation ANN with two inputs, one hidden layer with five hidden neurons and one output as the optimum network. The model is tested with actual time series data of inflation in case of Bangladesh and forecast evaluation criteria....

The performance of GA is measured and analyzed in terms of its performance parameters against variations in its genetic operators and associated parameters. Since last four decades huge numbers of researchers have been working on the performance of GA and its enhancement. This earlier research work on analyzing the performance of GA enforces the need to further investigate the exploration and e...

There are a lot of intensive researches on handwritten character recognition (HCR) for almost past four decades. The research has been done on some of popular scripts such as Roman, Arabic, Chinese and Indian. In this paper we present a review on HCR work on the four popular scripts. We have summarized most of the published paper from 2005 to recent and also analyzed the various methods in crea...

This paper proposes a new algorithm for finding minimum spanning tree (MST) of a weighted graph which is intrinsically parallel, unlike Kruskal’s algorithm. As far as the running time of the algorithm is concerned, it is faster than both Kruskal’s and Boruvka’s algorithms. However the Prim’s algorithm is bit faster than the proposed algorithm. The parallel implementation of the proposed algorit...
