As WLANs have become popular in many sectors, so we have to manage it efficiently. In a typical deployment of WLANs, the coverage areas of nearby access-points(APs) usually overlap with one another and a host may detect signals from multiple APs which degrade the network performance. The main purpose of our work to minimize the number of active APs in a overcrowded WLAS and to develop a bandwidth sharing techniques to reduce the wastage of bandwidth. This study represents the management of APs in overcrowded WLANs. In this thesis, firstly, we analyze the relationship of number of access point (AP) and achieved throughput for a given scenario. In the scenario we consider a number of parameters, i.e. given area, topology, number of users, expected rate and channel allocation vector. We find that in general with the increase of AP the performance of overall network improve. However after a certain number of deployed APs, further increase of AP does not bring substantial improvement in the network performance. More specially, performance deteriorates after a threshold value of number of APs due to increasing interference between adjacent channel (or co-channel) interference. We verify the throughput increasing rate with proper management of APs by simulation results using WIMNET (Wireless Internet-access Mesh Network) simulator.

GSM module is used for receiving short message service (SMS) from user’s mobile phone that automatically enable the controller to take any further action such as to switch ON or OFF the home appliances such as lights, airconditioners, fans, water pumps, door locks, TVs etc. Hardware of the system has been developed using an Arduino Uno board, a GSM modules, some switching relays and some other easily available electronic components. The driving software has been made using the Arduino IDE. The system is activated when only the user sends the SMS to the controller at home with the exact password. Upon receiving the SMS command, the microcontroller unit will decode the received SMS automatically and controls the electrical home appliances by switching ON or OFF the device according to the user direction.

It is considered a promising solution for high data-rate and short-range wireless communication system to meet an ever-growing demand for high speed. This technology is developed to transfer data at high rates over short distances at a very low frequency. Before 2001 UWB's application was limited mainly in military areas and gradually Federal Communications Commission (FCC) has allowed the commercial usage of the bandwidths of UWB. FCC regulates the frequency for the UWB technique is from 3.1ghz to 10.6ghz and the linear band is 500 mhz. In this paper, we've mainly focused on its applications in different arenas. This paper also represents its technological challenges, the advantages, and drawbacks as well as future work scopes.
