The conventional clustering algorithms in data mining like k-means algorithm have difficulties in handling the challenges posed by the collection of natural data which is often vague and uncertain. The modeling of imprecise and qualitative knowledge, as well as handling of uncertainty at various stages is possible through the use of fuzzy sets. Fuzzy logic(More)
Nowadays, due to wide applicability of Wireless Sensor Network (WSN) added by the low cost sensor devices, its popularity among the researchers and industrialists are very much visible. A substantial amount of works can be seen in the literature on WSN which are mainly focused on application specific WSN considering its resource constraints, neglecting the(More)
This paper examines the effect of different information access strategies on power consumption and information reliability, considering the wireless sensor network as the source of information. Basically, the paper explores three different access strategies, namely; reactive, periodic and hybrid and computes power consumption and mismatch probability [1] in(More)
Accessing information remotely to dynamically changing information elements cannot be avoided and has become a required functionality for various network services. The fact that most information is dynamic and changes value over time, leads to potential risk of using wrong information by the user due to several factors. The risks of using mismatching of(More)
Information and Communication Technology (ICT) plays an increasingly greater role in the development of nations. It has become an indispensable tool for achieving international goals such as the United Nations Millennium Development Goals (MDGs). However, the poor connectivity of Internet in the least developed countries is one of the major factors(More)
