Description: Energy consumption is prominent and critical issue faced by wireless sensor networks.
The maximum amount of energy is consumed when the sensors communicate with each other.
Therefore energy efficient routing mechanisms are required. In this paper, a routing scheme based
on the fisheye state routing with a difference in route selection mechanism has been proposed to
ensure the reduction in the overall energy consumption of the network. This scheme is named as
Energy-Aware Fisheye State Routing (EA-FSR). It is simulated considering various parameters
using QualNet5.0. Performance of EA-FSR has been compared with the original fisheye state routing algorithm which is also simulated in the same environment. For comparison various parameters
like end-to-end delay average, energy consumption and throughput have been considered. Platform: |

Description: Wireless sensor networks with mobile sink are ex-pected to increase the flexibility for gathering information in large-scale sensing and detecting environments. Energy saving becomes one of the most important features of the sensor nodes to extend their lifetime in such networks. A novel tree-based power saving scheme is proposed in this paper to reduce the energy consumption in wireless sensor networks with mobile sink. We adopt a dynamic sorting algorithm to create a tree-cluster routing structure for the sensor nodes. The main goal of this scheme is to reduce the data transmission distances of the sensor nodes by employing the tree structure and multi-hop concepts. Based on the location of mobile sink, the distances between the sensor nodes, and the residual energy of each sensor node, the proposed scheme makes an efficient decision for creating the routing structure. The energy consumption is reduced and the lifetime is extended for the sensor nodes by balancing the network load. Platform: |

Description: he main focus of this project is to develop an algorithm for keeping the household energy
consumption below a limit specified by the utility, during peak hours. By shifting the household
energy consumption to off peak hours, the total demand of the power grid can be reduced during
peak hours and thereby the probability of power grid failures as well as overloading of the network
elements can be reduced. As a result, the electricity cost can also be reduced. Platform: |

Description: Energy cost of transmitting a single bit of information is approximately the same as that needed for processing a thousand operations in a typical sensor node. Thus, a practical way to prolong a wireless sensor network lifetime is to reduce the sensor energy consumption in data transmissions. Data aggregation is an efficient way to minimize energy consumption on sensors. In this paper, we propose a practical secure data aggregation scheme, Sen-SDA, based on an additive homomorphic encryption scheme, an identity-based signature scheme, and a batch verification technique with an algorithm for filtering injected false data.

Description: Localization is one of the key techniques in wireless sensor network. The location estimation methods can be classified into target/source localization and node self-localization. In target localization, we mainly introduce the energy-based method. Then we investigate the node self-localization methods. Since the widespread adoption of the wireless sensor network, the localization methods are different in various applications. And there are several challenges in some special scenarios. In this paper, we present a comprehensive survey of these challenges: localization in non-line-of-sight, node selection criteria for localization in energy-constrained network, scheduling the sensor node to optimize the tradeoff between localization performance and energy consumption, cooperative node localization, and localization algorithm in heterogeneous network. Finally, we introduce the evaluation criteria for localization in wireless sensor network. Platform: |

can potentially perform offloading of computational tasks to

availability of computational resources, and link connectivity,
and find a balance between energy consumption costs of mobile

an optimization problem to minimize the latency while meeting

Description: The reliable data delivery is a challenging task in Wireless Sensor Networks (WSNs) due to dynamic and unpredictable changing behaviors of nodes. The traditional cryptographic and authentication based schemes can’t be adopted due to their associated cost and incapability to counter nodes misbehavior attacks. Recently, trust based solutions have proved to be more effective to address nodes’ misbehavior attacks. Apart isolating misbehaving nodes, the existing trust based schemes lacks the capability to minimize link failure notifications due to transient transmission disruption which consequently give rise to frequent route breakages thereby undermining throughput and route stability. Moreover, the existing solutions give rise to high energy consumption and control overhead in pursuit of trust estimation and network-wide dissemination which not only adds to network congestion but also undermines network lifetime.
