BETTER QUALITY OF SERVICE MANAGEMENT WITH FUZZY LOGIC IN MOBILE ADHOC NETWORK
Quality of service (QoS)is a great concept in mobile Adhoc network (MANETs). It is of a great importance that we are veryconscious of how packet is routed to maximize efficiency and minimize delay. In this paper, an efficient algorithm fortransmitting packet for better quality of service in adhoc mobile network was proposed. Fuzzy Self Organizing Map (FSOM)provide very efficient algorithmic tools for transmitting packet in an efficient manner by taking the most efficient route andalso the bandwidth, latency and range are considered to determine how good is the data delivered. The results shown thatfuzzy logic can guarantee QoS of every packets inthe network.Key words: Keywords – QoS, Adhoc network, Packet and Fuzzy logic
Distributed Range-Free Localization Algorithm Based on Self-Organizing Maps
In Mobile Ad Hoc Networks (MANETs), determining the physical location of nodes (localization) is very important for many network services and protocols. This paper proposes a new Distributed Range-Free Localization Algorithm Based on Self-Organizing Maps (SOMs) to deal with this issue. Our proposed algorithm utilizes only connectivity information to determine the location of nodes. By utilizing the intersection areas between radio coverage of neighboring nodes, the algorithm has maximized the correlation between neighboring nodes in distributed implementation of SOM and reduced the SOM learning time. An implementation of the algorithm on Network Simulator 2 (NS-2) was done with the mobility consideration to verify the performance of the proposed algorithm. From our intensive simulations, the results show that the proposed scheme achieves very good accuracy in most cases.</p
