    ABSTRACT: Wireless Network is spreading all over the world. Wireless network are very easy in installation and in use. This type of network does not require any extra cost in establishment. Every network has its advantages and disadvantages. A user faces many problems during using this network. Wireless networks are established in two variant modes either in infrastructure mode or in Ad hoc mode. Working in infrastructure mode is some where similar to wired network. Data transmission is achieved with the help of centralized device. Ad hoc mode works in decentralized manner. All data transmission done through the nodes present in the network. Ad hoc mode has many challenges like limited bandwidth, limitation of battery power, less memory space, data forwarding techniques, route selection, size of data etc. Resources required during data transmission may not be available in large amount. This may interrupt overall working of network. Ad hoc mode is easily deployable. Network can be established any time any where. Popularity of such network is increasing day by day. Battery power is one of the main issues in working of Ad hoc mode. Overall working and lifetime of Ad hoc network is totally dependent on power available at a node. Power consumption in data transmission depends on distance between two nodes. Large distance may consume lot of battery power. Route selection, Network information distribution and retransmission of data also consumes noticeable amount of battery power. If a node spends very large part of its battery power in few data transmission then it may no longer be available to other nodes in the network. Such types of node are excluded from network path. In this paper it has been analyzed that data transmission depends on the distance between two nodes as well as on environmental condition. Environmental condition may affect data transmission.

    ABSTRACT: This paper presents the development of E - School System Architecture (ESSA), the architecture for an E-Learning System. This architecture is introduced for the purpose of providing flexibility, scalability and modularity to the E-Learning system. Its main objective is to propose an architecture under which different e-learning software modules can be developed and integrated. During the course of development of this architecture, different services needed for an E-Learning system are identified, together with their functional understanding and means of technological realization. ESSA is motivated by MVC Architecture. It has a model that represents the data for the application, the view that is the visual representation of that data and a controller that takes user input on the view and translates that to changes in the model. It is developed for School of Computer Science & IT, DAVV, Indore. A prototype (ESS) is being built to verify and validate this architecture.

    ABSTRACT: Wireless network is an emerging area for researchers. Wireless network can be deployed either in infrastructure mode or in Ad hoc mode. In an Infrastructure mode, mobile stations communicate with each other with the help of Base Station or Access Point (AP). It is similar to star topology of wired network. This Access Point makes communication easier between the nodes. In an Ad hoc mode there is no access point or base station that helps in communication between nodes. All nodes in wireless Ad hoc network directly communicate with each other in peer-to-peer fashion. The topology of wireless Ad hoc network is dynamic in nature therefore routes are changed frequently. Wireless Ad hoc network has no routers. Each node act as an intermediate node for other node and intermediate node forwards data towards destination node. An intermediate node is also a sender for other nodes and acts as a router in the network. The major factors, which affect the data transmission of an Ad hoc network, are battery power, bandwidth, delay, speed, type of data and cost. The data transfer rates in a wireless Ad hoc network are not static but are dynamic. The availability of these resources at any node, either during data transmission or forwarding of data to other node is not certain. The resources available at any node are in scarce. The optimized use of any of these resources is a big question. Battery power is one of the major factors in a wireless Ad hoc network. A node can transmit data to a longer distance only if it has sufficient battery power. Area covered by a node in an Ad hoc network plays an important role during data transmission. In this paper our main focus is on utilization of battery power available at any node for data transmission. Here we propose two algorithms for optimization of battery power that find out nodes which wants to transmit the data and the total power consumption in wireless Ad hoc network.
