Abstract

The underwater wireless sensor networks poses many challenges due to critical underwater environment such as large propagation delay and limited bandwidth capacity of acoustic channels. The sensor nodes under mobility causes the problem of delay, more energy consumption and undetermined propagation losses. In this paper we propose a routing protocol based on geographical dynamic routing (DTDRP) to address some of these problems. We focus on minimizing the delay and maximizing the throughput thereby increasing the energy efficiency. The simulations are carried out to analyze the performance of the proposed algorithm by comparing with the existing protocols in underwater environment conditions.

Keywords

Underwater Wireless Sensor Networks, DTDRP, Underwater Topology, Performance Analysis.

Abstract

The popularity of home automation has been increasing greatly in recent years due to much higher affordability and simplicity through various available technologies. A home automation system integrates electrical devices in a house with each other. The main goal of automation is to reduce human effort and save power. The proposed technique is based on controlling the equipments by measuring the parameters of motion detector, temperature sensor, LDR and smoke sensor. The sensed signals are processed using signal conditioning unit based on the requirements. The microcontroller captures the entire signal and instructs the device to operate accordingly. The electrical equipment like light, fan, refrigerator and alarm are interfaced with microcontroller by suitable drive circuit. The microcontroller also derives an LCD to provide a simple user interface. The master control of the whole circuit lies in operation of magnetic switch which depends on opening and closing of the door.
