A dynamic two hops reputation assignment scheme for selfish node detection and avoidance in delay tolerant network

Abstract: In recent years Delay/Disruption Tolerant Network (DTN) has been identified as the most promising and challenging areas of wireless communication where sparseness and delay are particularly high. It is emerging as a promising network in the areas of disaster response, inter-planetary, vehicular, military/tactical, underwater, satellite networks. DTN is characterized by the large communication latency and lack of end to end path from source to destination. Due to intermittent connectivity in DTN, data forwarding is possible using multiple hops in "store-carry-forward" manner. So, the entire data communication is solely dependent on the cooperation of the intermediate nodes or hops. However, these intermediate nodes sometimes may become selfish due to preserve its limited resources or due to some malicious intention [1][2]. In order to increase data delivery, the detection and avoidance of such selfish nodes are foremost required. Here we are using reputation based strategy where reputation can be used as a measure to detect the cooperation pattern of a node with other nodes in the network during data communication. In this paper, we propose a dynamic two hops reputation technique for detection and avoidance of selfish nodes where neighbor nodes will monitor the behavior of a particular node as forwarder and receiver. These one hop and two hops neighbor nodes will give their feedback after data communication takes place at certain interval. However, the universal reputation matrix will be published time to time based on the cooperation pattern of nodes by the Trusted Authority (TA). The performance of the proposed scheme was evaluated on ONE simulator [3].

MHRP: A novel mobility handling routing protocol in Wireless Body Area Network

Abstract: For the last few years a lot of research work has been carried out on the applications and other aspects of Wireless Body Area Networks (WBAN). Majority of this work are found on healthcare domain. In WBAN, sensor nodes are used either as wearable or as implant devices. These devices collect information from the human body and transmit them wirelessly to remote server which is viewed and analyzed by the concerned persons sitting in their chambers. But, the link between the WBAN and the remote server changes frequently due to the movement of human body. As such maintaining seamless connectivity in such environment is a challenge of current research work. In this paper, a novel Mobility Handling Routing Protocol (MHRP) for WBAN has been proposed. The proposed protocol is faster, reliable, takes care of human mobility through posture detection and ensures seamless connectivity. In support of better performance of the proposed algorithm, analytical comparison with related existing works is given.

Minimal Spanning Tree in Cylindrical Single-Valued Neutrosophic Arena

Abstract: In this chapter, the concept of cylindrical single-valued neutrosophic number whenever two of the membership functions, which serve a crucial role for uncertainty conventional problem, are dependent to each other is developed. It also introduces a new score and accuracy function for this special cylindrical single valued neutrosophic number, which are useful for crispification. Further, a minimal spanning tree execution technique is proposed when the numbers are in cylindrical single-valued neutrosophic nature. This noble idea will help researchers to solve daily problems in the vagueness arena.

An efficient call admission control scheme on overlay networks using fuzzy logic

Abstract: This paper proposes a call admission control (CAC) scheme for heterogeneous wireless overlay networks (WONs) that combine the benefits of the three commonly used techniques- guard channel, buffer management and priority scheduling with fuzzy logic application. The simulation results show that the scheme is extremely efficient offering a high degree of quality of service (QoS).
