Most of the localization algorithms proposed for sensor networks are based on Sequential Monte Carlo (SMC) method. To achieve high accuracy in localization it requires high seed node density and it also suffers...

    Performance Evaluation of Relaying Schemes for Wireless Communication Systems

    The evaluation of MIMO (Multiple-Input Multiple-Output) Relay wireless system is carried out and compared against the performance of a SISO (Single-Input Single-Output) Relay wireless system. The encoding scheme used in MIMO is Alamouti coding and decoding is done by the Maximum Likelihood (ML) detector. A comparison is made between the...

    A Fuzzy Based Approach in Multihop Network

    The proposed system utilizes the concept of multi hop communication in Wireless Sensor Networks (WSNs). On the other hand, the single hop communication leads to more power dissipation in the nodes at the time of transmitting sensed data. The proposed system rectifies the above mentioned problem with the multi hop...

    EARM: An Efficient and Adaptive File Replication With Consistency Maintenance in P2P Systems

    In p2p systems, file replication and replica consistency maintenance are most widely used techniques for better system performance. Most of the file replication methods replicates file in all nodes or at two ends in a client-server query path or close to the server, leading to low replica utilization, produces unnecessary...
