Smart Home Security based on optimal wireless sensor network routing protocols

Smart Home Security is designed to provide better security as well as energy efficiency and comfort. The paper presents a proposed smart home security (SHS) based on PIR Motion detector and MQ 9 Gas detection sensor. These sensors are monitored remotely by employing the communication networks. But the communication may be subject to delay, data loss and transmission congestion. The major challenge for smart home security is how to determine the suitable routing protocol, that ensures the data transmitted from a node to the other node as fast as possible. The paper makes a performance comparison between the Destination Sequenced Distance Vector and Ad hoc On Demand Distance Vector routing protocols which is presented in two scenarios, with different nodes, pause period and node speed by using Network Simulator-2 on Linux platform. The evaluation criteria of the protocols is tested for delay time, data delivery ratios with routing overload parameters. It is observed that DSDV offers better performance compared to AODV for SHS while DSDV has lesser routing carry and delay time compared to AODV.

Efficient electrocardiogram data compression algorithm based on wavelet transform

Physicians as the most important tool in the diagnosis of acute and chronic heart conditions leverage the Electrocardiogram (ECG) data. The huge volume of data that needs to be gathered; processed as well as transmitted burdens the communication channel by obstructing the implementation of the ECG applications in telemedicine and remote monitoring scenarios. This has triggered the need for computationally efficient and advanced compression methods permitting the reconstruction of the destinations original signal. This paper focuses on proposing a highly efficient compression method relying on both run length coding (RLC) and fast lifting wavelet transform (FLWT) for both 1 and 2 dimensional ECG data. The basic wavelets that had been used are Daubechies (Db4); Cohen-Daubechies-Feauveau (CDF 2.2) and Haar. The algorithm that has been proposed is deployed as well as tested on different ECH data signals that stem from an open MIT-BIH arrhythmia database. It has been seen that Db4 offers greater performance via lower error and greater compression ratio when opposed to the other wavelets stated here.

Improved performance of energy consumption in wireless sensor networks based on ZigBee transceiver protocol

One of the major weaknesses of Wireless Sensor Networks (WSNs) is the energy consumption because of limited battery resource and battery replacement or recharging difficulty. The energy consumption can be controlled in WSNs by more than one layer. The research presented in this work aims to reduce the energy consumption in the physical layer because most of the energy consumption occurs in this layer. Furthermore, such use will also enhance energy efficiency, bit error rate (BER), and throughput of the wireless sensor network. In this work, the WSNs nodes are divided into five clusters. Also, four different systems have been proposed according to the type of transceiver technique used in WSNs. The proposed four systems are analyzed, simulated and evaluated with the Additive White Gaussian Noises (AWGN) and Rayleigh flat fading channels. The results show that system 4 achieves the best energy efficiency performance compared with the other three systems at lower SNR up to −4dB. While, system 1 achieves better energy efficiency performance at high Signal to Noise Ratio (SNR) from 23dB and more.
