Mobile ad hoc network is a collection of mobile nodes communicating through wireless channels without any existing network infrastructure or centralized administration. Because of the limited transmission range of wireless network interfaces, multiple "hops" may be needed to exchange data across the network. In order to facilitate communication within the(More)
Mobile ad hoc network is a reconfigurable network of mobile nodes connected by multi-hop wireless links and capable of operating without any fixed infrastructure support. In order to facilitate communication within such self-creating, self-organizing and selfadministrating network, a dynamic routing protocol is needed. The primary goal of such an ad hoc(More)
OBJECTIVE The aim of the present study was to determine the impact of universal salt iodization (USI) on the prevalence of iodine deficiency in the population of an area previously known to have severe iodine deficiency in India. DESIGN In a cross-sectional survey, a total of 2860 subjects residing in fifty-three villages of four sub-districts of Gonda(More)
Routing Algorithms are driving the growth of the data transmission in wireless sensor networks. Contextually, many algorithms considered the data gathering and data aggregation. This paper uses the scenario of clustering and its impact over the SPIN protocol and also finds out the effect over the energy consumption in SPIN after uses of clustering. The(More)
Clustering is an important research area for mobile ad hoc networks (MANETs) as it increases the capacity of network, reduces the routing overhead and makes the network more scalable in the presence of both high mobility and a large number of mobile nodes. In clustering the clusterhead manage and store recent routing information. However the frequent change(More)
Security has always been a great concern whenever there is communication between sender and receiver. To overcome the issues of security breaches many cryptographic algorithms are used like: AES, DES, Triple DES, Blowfish, etc. The objective of this paper is to enhance and evaluate the Blowfish algorithm on the basis of different parameters like Encryption(More)
Routing Algorithms are driving the growth of the data transmission in wireless sensor network. Contextually, many algorithms proposed for efficient data transferring. This paper uses the scenario and node distribution across the Battle field in India. This Paper uses clustering algorithms to send the data over different geographic region. During the Battle,(More)

This paper presents a scheme, in which the collaborative efforts of limited number of sensor nodes provide the social guidance for localization process to be used for uniform distribution of the clusters, over the network area. Utilizing the information provided in the form of gbest value and the direction for position update as social guidance, the sensor(More)
Non uniform energy consumption of the nodes is a major area of concern in cluster based data gathering architectures proposed for wireless sensor networks in the literature and is an active area of research over recent past years. The solutions suggested in the literature, for uniform distribution of energy consumption, require rotation of clusterhead role(More)
