In this paper, we present and compare three clustering approaches which group fingerprints according to its minutiae points locations. The best technique for grouping fingerprints is based on the ART1 clustering algorithm. We compare the quality of clustering of ART1 based clustering with k-mean clustering technique and self organizing neural network (SOM) [1] clustering algorithm in terms of intra-cluster...
In the recent years, wireless technology has enjoyed a tremendous rise in popularity and usage, thus opening new fields of applications in the domain of networking. One such field concerns mobile ad hoc networks (MANETs) where the participating nodes do not rely on any existing network infrastructure. By definition, the nature of ad hoc networks is dynamically changing and they have a fully decentralized...
In this paper, we present a novel approach to group fingerprints according to its minutiae point's locations. Our technique for grouping fingerprints is based on the ART1 neural network. We compare the quality of clustering of our ART1 based clustering technique with that of the self organizing neural network (SOM) clustering algorithm in terms of intra-cluster distances. Our results show that the...
This paper presents modification of span for wireless mobile ad hoc networks. Span is an energy efficient coordination algorithm for topology maintenance in wireless ad hoc networks. Each node in span does the local decision on whether to announce for or withdraw from coordinator. We modify coordinator withdrawal procedure of span by adding average speed of node as one of the condition for withdrawing...
This paper presents energy aware greedy routing (EAGR) scheme for wireless ad hoc networks. In this scheme, the cost metric of a node depends on the following parameters of a neighboring node: (1) Distance from the destination, (2) fraction of energy consumed, and (3) rate of energy consumption. When a node has the least cost metric, the packet is forwarded to that node. We evaluate the performance...
