A New Approach to Trace the Behaviour Pattern of Nodes in the Delay Tolerant Network

Abstract: Due to lack of features of traditional network characteristics, DTN becomes one of the promising research paradigms of wireless network. As there are intermittent connectivity and store-carry-forward features, end-to-end acknowledgement is not possible. DTN is also named as ‘opportunistic network’. But interestingly, intermediate nodes may always not behave fairly. Sometimes, due to limited resources (bandwidth and memory) intermediate nodes may behave ‘selfish’. Intermediate nodes may also behave unfairly to next hop node intentionally. This behaviour is known as ‘misbehaving behaviour’. Recent studies on ‘selfish node’ and ‘misbehaving node’ show us the negative impact on network performance (delivery ratio, delivery cost, delivery latency). So we design a slightly new concept inspired by real-life application in our paper showing the positive aspect of the involved nodes in the network. Apart from participating in data forwarding, node may behave as ‘traffic node’ trying to show the right path towards destination.

Mobility Management Issues for Next Generation Wireless Networks

Abstract: The next generation networks must support mobility for ubiquitous communication between any two nodes irrespective of their locations. Mobile IP was the first protocol to support mobility. The process of registration in Mobile IP protocol requires large number of location updates, excessive signaling traffic and service delay. This problem is solved by Hierarchical Mobile IP (HMIP) using the concept of hierarchy of Foreign Agent (FA) and the Gateway Foreign Agent (GFA), Mobility Anchor Point (MAP) to localize the registration information. The performance depends upon the selection of GFA or MAP and some key parameters. This chapter discusses several HMIP based mobility management schemes with a comparative analysis of those protocols and proposes an efficient mobility management scheme.

Design and analysis of large unity gain bandwidth operational amplifier for low-voltage applications

Abstract: This work deals with the design and analysis of large unity gain bandwidth operational amplifiers for low voltage applications. Conventional and dynamic threshold MOSFET (DTMOS) based design approaches of Op-Amp in sub-threshold and near-threshold regime have been chosen to achieve larger unity gain bandwidth. Extensive simulations have been done using TSPICE for 90nm and 180 nm separately.42 dB DC gain and 704 KHz unity gain frequency can be achieved in sub threshold region using proposed DTMOS structure. For lower technology node, i.e., for lower gate length of MOSFET, significant improvement in unity gain frequency has been observed. Simulated results demonstrate that the proposed op-Amp is suitable for the low voltage application which requires higher bandwidth. Besides, analysis of Op-Amp in near threshold regime would be promising for the IoT applications.

Multiple fault detection technique for digital microfluidic based biochip

Abstract: Faults in biochips degrades the performance of the biochips. This paper describes a new multiple fault detection technique for digital micro fluidic based biochips. The microfluidic based biochips are most important revolutionizing laboratory procedures use at a vast scale, e.g., bio sensing, clinical diagnostics etc. Due to mixed energy domains this micro fluidic based biochip exhibits unique failure mechanism and need to be error free to ensure system dependability. In this paper a new advance technique is presented to traverse all the cells and cell boundary in much more less time compared to some previous technique to detect multiple faults.
