Among the mobile applications contributing to the surging Internet traffic, video applications are some of the biggest contributors. Most of these video applications use HTTP/HTTPS tunneling making it difficult to apply port based or packet data based identification of flows. This makes it challenging for network operators to enforce bandwidth regulation policies for app based service differentiation...
With a wide scope to explore and harness the oceanic sources of interest, the field of underwater wireless sensor networks (UWSNs) is attracting a growing interest of researchers. Owing to the real-time remote data monitoring requirements, underwater acoustic sensor networks (UASNs) emerged as a preferred network to a great extent. In UASN, the limited availability and non-rechargeability of energy...
The magnetic induction (MI)-based communications assume the applications, wherein standard electromagnetic (EM) wave and acoustic communications are not effective. The EM and acoustic-based communications do have high power loss, high propagation delays, very low data rates, and environment-dependent channel behavior. MI communications heavily depend upon the time varying magnetic field to convey...
Wireless sensor network is an emerging technology due to its wide range of application. This scheme proposes a new secure protocol with better security and Even-driven cluster formation brings energy efficiency by avoiding the unnecessary formation of clusters, when no event is there in the network The proposed scheme adopts a level based secure hierarchical approach to maintain the energy efficiency...
This paper aims at providing a solution to the problems faced in the existing analogue water meters that include the low accuracy in flow measurement, air valve issue, manual billing system and uneven distribution of water. The SMART AQUA METER-SAM overcomes these limitations by introducing a smart electronic measurement system. It automates the billing system using a low power wireless technology-ZigBee[1]...
Enhancing the living standards of elderly people is important, and providing them with proper care at the time of emergency is necessary. Unintentional falls often result in an emergency situation for seniors. A novel approach based on efficient pre-fall detection is used to develop a system with smart wireless sensors that provide monitoring and protection for seniors and patients from a fall occurrence...
