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.

Description: One of the most critical issues in the wireless sensor networks is the network s nodes limited availability of energy. The network lifetime strictly depends on its energy efficiency.
Clustering is a method to make the consumed energy efficient. LEACH is one of the fundamental clustering algorithms. In
this paper we have proposed an algorithm which extends LEACH by considering number of neighbors and remaining of the energy of each node to be a cluster head. We have also proposed to use gateway nodes in each cluster to enable the
cluster head to reduce its transmission radius within the cluster to achieve better power saving. We analyze and compared the proposed algorithm along with the LEACH, LEACH-c and MIMO the most recent extend over the LEACH and show that the proposed algorithm can prolong the lifetime of the network.

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: 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: 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. Platform: |

Description: LEACH [1] is an autonomous adaptive clustering protocol that distributes the
energy load evenly among the sensors in the network using randomization. The
nodes organize themselves into local clusters, with one node acting as the local
base station or cluster head. In order to not drain the battery of a single sensor
randomized rotation of the high-energy cluster head position such that it rotates
among the various sensors. Once the cluster head has all the data from the nodes in
its cluster, the cluster head node aggregates the data and then transmits the
compressed data to the base station. Since it compress the amount of data being
sent from the clusters to the base station, energy dissipation is reduced and system
lifetime is thus enhanced.

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
