Description: In wireless sensor networks, owing to the limitation of energy, memory, and computation are necessary component to design the networks under the constraints. Prolonged network lifetime and reliability are the most common requirements for many wireless sensor networks applications.
I’d like to focus on two types of wireless sensor networks nodes Homogenous and Heterogeneous nodes. In addition, I’ll study an effective Technique which is clustering to achieve reliability in wireless sensor networks.

Description: Energy Harvesting wireless sensor network(EH-WSN) is a kind of WSN that
uses rechargeable power supply instead of using traditional battery.
In traditional WSN, the energy sources is limited. When the power source of
node nish, it can not continue to work unless it is recharged again. So the
eort was to design energy-e cient network protocols to maximize the lifetime
of WSN by minimizing energy usage.if we can have access to unlimited power, we can have in nite
lifetime in network. This unlimited power can be provide by environment such
as light, vibration and heat. Then stores the harvested energy in a storage
device. When the device uses energy harvested instead of battery, the residual
energy is no more an useful quantity to preserve. In EH-WSN, if the rate of
harvesting power is lesser than the power used by the node, the sensor node
should go to sleep to charge up. Platform: |

habitat monitoring in nature preserves, monitoring and gathering events in hazardous environments, surveillance of buildings, and
surveillance of enemy activities in a battlefield environment. Nodes in a sensor network are severely constrained by energy, storage capacity and computing power. To prolong the lifetime of the sensor nodes, designing efficient routing protocols is critical. Platform: |

Description: Wireless sensor networks (WSNs) enable new applications and require
non-conventional paradigms for protocol design due to several constraints. Owing to the
requirement for low device complexity together with low energy consumption (i.e., long

capabilities must be found Platform: |

Description: Energy efficiency is the most important design goal
for wireless sensor networks (WSNs). In this paper, we propose
an energy-efficient cooperative MIMO scheme, which
combines energy-efficient LEACH (EE-LEACH) protocol and
cooperative MIMO. We name it as EE-LEACH-MIMO
scheme. EE-LEACH is an improved LEACH algorithm, in
which the network is partitioned to sectors with equal angle for
avoiding the distribution non-uniformity of cluster heads. In
EE-LEACH-MIMO scheme, the location and the residual
energy of each node are considered when the cluster heads for
clustering and cooperative nodes for MIMO system are chosen.
For comparisons, LEACH, EE-LEACH, the simple
cooperative scheme with LEACH and MIMO (LEACHMIMO),
and EE-LEACH-MIMO scheme are simulated. The
result shows that EE-LEACH-MIMO scheme can well balance
the network load, save energy and prolong the network
lifetime Platform: |

Description: the network lifetime based on a new Energy-Aware Objective Function used to design a Routing Protocol for Low-Power and Lossy Networks. The proposed Objective Function uses the Expected Transmission Count Metric and the Remaining Energy on each sensor node to compute the best paths to route data packets across the network.So EAOF prolongs the network lifetime and reduces the need for human intervention on battery changing, thereby enhancing the system wearability and reducing operational costs.

Description: In wireless sensor networks, multipath routing is
used to alleviate reliability degradation due to multihop transmissions
over error-prone wireless channels. However, multipath
routing is not energy-efficient, as it requires all the nodes in the
network to always be awake. To prolong the network lifetime
while maintaining a certain reliability performance, we propose
Sleeping Multipath Routing, which selects the minimum number
of disjoint paths to achieve a given reliability requirement and
puts the rest of the network to sleep. Platform: |
