Description: Recent advances in wireless sensor networks have led to many new protocols specifically designed for sensor net-
works where energy awareness is an essential consideration. Most of the attention, however, has been given to the
routing protocols since they might di?er depending on the application and network architecture. This paper surveys
recent routing protocols for sensor networks and presents a classification for the various approaches pursued. The three
main categories explored in this paper are data-centric, hierarchical and location-based. Each routing protocol is de-
scribed and discussed under the appropriate category. Moreover, protocols using contemporary methodologies such as
network flow and quality of service modeling are also discussed. The paper concludes with open research issues. 2003 Elsevier B.V. All rights reserved.

Description: Abstract
This paper talk about the communication protocol named LEACH. The protocol focuses on reducing the power consumption of wireless sensor networks, which can have significant impact on the overall energy dissipation of these networks. LEACH uses localized
coordination to enable scalability and obustness for dynamic networks, and incorporate data fusion into the routing protocol to reduce the amount of information that must be transmitted to the base station. Simulations show that LEACH can achieve as much as a factor of 8 reductions in energy dissipation compared with conventional routing protocols. In addition, LEACH is able to distribute energy dissipation evenly throughout
the sensors, doubling the useful system lifetime for the networks we simulated. Platform: |

Description: In wireless sensor networks, the power resource of
each sensor node is limited. Minimizing energy dissipation and
maximizing network lifetime are important issues in the design
of routing protocols for sensor networks. In this paper, Cluster
routing protocol LEACH (Low-Energy Adaptive Clustering
Hierarchy) is research and improved. We extend LEACH
stochastic cluster-head selection algorithm via changing the
round time According to the situation of sensor network. It is
named Variable-round LEACH. The result simulated in NS2
shows that the energy is significantly reduced and the lifetime
of the whole network is increased compared with the previous
routing algorithm for the sensor networks. Platform: |

Description: Abstract—In recent years, as the development of wireless sensor networks, people do some deep research on clusterbased protocol, most about the prolongation of the lifetime of WSN and decline of energy consumed by the sensors .This article analyses the cluster-heads generating algorithm among LEACH and presents improved approach that adjusting the nodes, Threshold function. When non cluster-heads choose optimal cluster-head, they consider comprehensive nodes' residual energy and distance to base-station, then compare their performance, the simulation results show that the new strategy of cluster-heads election achieve great advance in sensor and networks' life-time Platform: |
