Description: Every consumer can buy a memory card (is nothing but an EEPROM IC) with a password stored inside it using a MC program. The memory card is available at various ranges (ie. Rs 50, Rs 100, Rs 200 etc).In our project we have given the name for memory card as smart card.
When the consumer insert a smart card into the card reader which is connected kit.Then the card reader will read the stored information and delete the information from the EEPROM IC(smart card) using the MC program. So that the smart card cannot be reused by others. Suppose if a consumer buy a card for Rs.50/- he / she can insert this amount through the card reader so that prepaid energy meter with tariff indicator kit will be activated. According to the power consumption the amount will be reduced. When the amount is over, the relay will automatically shutdown the whole system. In our project we also have a provision to give an alarm sound to consumer before the whole amount is reduced.

Description: The transmission range that achieves the
most economical use of energy in wireless ad hoc networks
is studied under homogeneous node distribution. By assuming
the knowledge of node location, we first proposed
a transmission strategy to ensure the progress of data
packets toward their final destinations. Then the average
packet progress for a transmission range universal for all
nodes is derived, which is accordingly used to determine
the optimal transmission range that gives the maximum
efficiency of energy consumption. Different from some
previous work, our analysis does not make the assumption
of large nodal density in the wireless ad hoc networks
studied. Numerical and simulation results are presented
to examine our analysis for wireless ad hoc networks. Platform: |

Description: To support simulations of S-MAC and other energy-efficient protocols, we have extended the energy model in ns-2. The old energy model did not have a sleep state. We added the sleep state. In addition, we also added energy consumption during state transition from sleep to idle (active). To help analyzing energy consumption in different states, we enhanced the energy traces on individual states: sleep, idle, transmit and receive. Platform: |

Description: A major issue with ad-hoc networks is energy consumption since nodes
are usually mobile and battery-operated. In this project we compared the
performance of ad-hoc routing protocols in a network where each participating
mobile node has a given battery life and will shut-down when a threshold is
reached. We studied two routing protocols, Dynamic Source Routing (DSR), and
Destination-Sequenced Distance-Vector Routing (DSDV), by comparing the node
termination rate as well as the over-all goodput of the network. From the
simulations we observed that in high node density, DSR performs better than
DSDV. The performance gap can be decreased by smaller number of nodes in the
network or more path loss and shadowing variance. Platform: |

Description: Abstract: The optimal number of cluster heads is an important parameter of wireless sensor network performance. Network nodes will consume more energy if the number of cluster heads is too much or too little. This paper focuses on novel calculation method for ptimal number of cluster heads. Base on the analysis of LEACH energy dissipation model,novel lation method is derived from the total energy dissipation of a round. Simulation shows the
relationship of the optimal number of cluster heads, the number of frames in steady state phase and the distance between cluster heads and base station (BS).And it provides a theoretical basis for calculation of optimal number of cluster heads which can reduce
the energy consumption among nodes and achieves
an improvement on the network lifetime. Platform: |

Description: Abstract—the application of wireless sensor network (WSN) is always restricted by the energy shortage of sensor nodes. In order to reduce the entire energy consumption of the WSN, a promising approach is to design light clustering algorithms.LEACH is such a well-known clustering algorithm that was designed to distribute the energy consumption to nodes in the WSN evenly. LEACH is characterized by its attactive clusterbased strategy however, in the algorithm, energy dissipation of
entire network is still great during the process that cluster-heads (CH) transmit data to base station (BS). In this paper, based on
LEACH, we propose a modified clustering orithm which is named ESCAL. In ESCAL, CHs won’t communicate with BS directly, but transfer aggregated data to the nearest node in term
of received signal strength then this elected nearest node willcompress and forward the data to BS.-Abstract—the application of wireless sensor network (WSN) is always restricted by the energy shortage of sensor nodes.
