Description: 目前，物联网备受关注。在多网关无线传感网络与物联网的异构融合中，通过网关连接是最常用的策略。本程序基于贪心算法，寻找每个节点至多个网关的最优路径，并将流量按比例分配给各网关。-
Recently, the Internet of Things is getting more and more attention.There are different approaches to integrate WSN into the Internet. The most usual one is to connect the WSN and the Internet through gateways. This program makes uses of the greedy algorithm to find the optimized path from each node to multiple gateways. Then, the traffic from the source node is allocated to each gateway.

Description: Alternative Path-based Congestion Control in WSN设计了一种用于多对一的网络中的资源聚合的机制，-we design a mechanism using spare
resources to mitigate congestion in a many to one network.We
classify the node congestion into two categories according to the
reasons and propose two distributed algorithms which can find
an alternative path using the neighbor table efficiently.At the
end of this paper,we simulate the drop rate of WSN to evaluate
our mechanism.The simulation shows that using our mechanism
improves network transmission quality significantly.

Description: The cluster head is selected by the random number
generated by nodes in the hierarchical routing protocol which
is implementing Low Energy Adaptive Clustering Hierarchy
(LEACH). As a result, the cluster head may be chosen
randomly and be distributed asymmetrically. Focus on this
problem, this paper introduces a function to improve the
problem. This function uses the relative distance between
nodes and base station and the round number as its
parameters. Hence, the distribution of cluster head can be
symmetrical through changing parameters of the function,
and. With the increasing of running time, every node in the
network has the chance to be a cluster head, that is, the energy
consumption could be balance. The simulation result shows
that the lifetime of Wireless Sensor Network (WSN) has been
prolonged about 14 .

Description: —As WSN is a resource-constrained network,
especially the limited energy, so it must maintain smaller
router information and reduce the energy consumption as
much as possible. This paper briefly introduces the wireless
sensor network, and analysis the problems existed in
LEACH routing protocol. Put forward the improved
algorithm based on LEACH cluster head multi-hops
algorithm, and under considering the premise of node
energy, consider the optimum number of cluster head and
selecting cluster node ,and through the use of limiter the
number of nodes in each cluster to balance the energy
depletion of each node. It could balance energy
consumption and prolong the lifetime of sensor network
through the use of algorithm. Emulation result indicates it
is effective.-—As WSN is a resource-constrained network,

Description: we have discussed HCTA based tracking and single hop routing and LEACH based
tracking and clustering routing. LEACH based tracking is divides sensor nodes in cluster. In each
cluster CH (cluster head) applies aggregation process on packets then directly transmits to sink node.
Thus, minimum packets transmit and packets does not route entire sensor nodes in WSN. CHs in
clusters transmit packets based on carrier sense multiple access collision avoidance (CSMA/CA), to prevent collision and minimize transmission and reception process. Overall energy conserve by LEACH during simulation is same.

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.
