One major Disadvantage of OFDM is the high peak-to-average Power ratios (PAPR). There is a procedure for Selected Mapping (SLM) is PAPR reduction techniques for Orthogonal Frequency Division Multiplexing (OFDM). But these reduction techniques produce high computation complexity which is costly and time consuming. In this paper we proposed a scheme to reduce the computational complexity of SLM technique...
This paper discussed interoperable biomedical devices. This topics discussed environmental functional architecture, MDIE communication protocol, MDIE operational architecture, attack vectors for IMD communication, system model, threat model, secure channel establishment, physical security, access control, evaluation metrics, regulatory aspects and other related topics.
In this paper, a new protocol termed CoopXLM that integrates cooperative communication and Cross-Layer Module (XLM) is created and examined via simulation. CoopXLM modifies XLM by allowing multiple cooperative nodes to participate in receiver-based contention. Although there is increased energy consumption for processing, simulation results indicate that across all duty cycles there is an average...
Wireless sensor network is need of present era or advanced technology. In this paper we have presented the details of methodology followed for implementation of a wireless sensor network in a process plant for based solution for data acquisition in a process plant. Due to its specific approach the solution not only acquires the data but also serves very effectively as a maintenance and diagnostic...
Multi-carrier system has been fuelled by large demand on frequency allocation, resulting in a crowded spectrum as well as large number of users requiring simultaneous access. Existing wireless systems may be utilized single frequency, single antenna and pulse for carrier transmission and reception. Problems of such system is that in case of failure the total system will become non operational. So...
Previously, we have developed a framework to perform systematic analysis of CSMA/CA based wireless MAC protocols. The framework first identifies protocol states that meet our study objective of minimizing a given performance metric. It then applies search techniques and heuristics to construct sequences of protocol events in a given topology that satisfy our objective. In this paper, we demonstrate...
