What is MWSNs?
❑Mobile Wireless Sensor Network (MWSN) is defined as a wireless sensor network (WSN) in
which the sensor nodes are mobile.
❑Mobile sensor nodes consist of a microcontroller, various sensors (i.e., light, temperature,
humidity, pressure, mobility, etc.), a radio transceiver, and that is powered by a battery.
➢ Designed with one or more
➢ The location or position finder
unit is used to identify the
position of the sensor node
➢ The mobilizer provides mobility
for a sensor node
➢ The power generator unit is
responsible to generate a
power for recharging battery.
Challenges Faced By MWSNs
➢Limited battery power.
➢Low complexity algorithms required for
➢Use of only a simplex radio.
➢Hybrid topology is the solution for data
collection, network performance and
➢ Modeled to describe the
movement towards/away mobile
➢ Tells us About how Location,
Velocity and Acceleration
change over time.
➢ Mobility Management Schemes
For MWSNs describe the use of
mobility models to predict
future position of sensor nodes.
➢ Transfer the data onto the mobile
sensor nodes to the sink/base
➢ Then, The sink and the remote
user/server are connected by the
➢ MWSNs purely depend on Data
Collection or Topology
➢ Define the dimension of the
sensor node group, manage the
addition of new members of a
group and deal with the
withdrawal of members that leave
➢ The routing protocols define
how nodes will communicate
with each other and how the
information will be disseminated
through the network.
➢ The routing approaches to the
MWSNs can be centralized,
distributed or hybrid.
Node Centric Routing
Data Centric Routing
Source Initiated Routing
(Low-energy adaptive clustering hierarchy)
➢ Routing protocol
➢ Organizes the cluster such that the
energy is equallydividedin all the
sensor nodes in the network.
➢ Several clusters are produced of
➢ One node defined as cluster head act
as routing node for all the other nodes
in the cluster.
➢ Sensor nodes elect themselves as
cluster head with some probability
criteria defined by the protocoland
announcethis to other nodes.
➢ It uses the Hierarchical Tree Topology.
➢ There are two phases
➢ Topology Construction Stage
➢ Data aggregation tree
➢ Cluster structure
➢ Multi-hop transmit
➢ Topology Maintenance Stage.
➢ Follows Multi-Hop Scheme
➢ Member Nodes Mobile
➢ Cluster Mobile Reaction
➢ T-Leach is Efficient Than Leach in
terms of packet delivery ratio and
average energy consumption.
❑Scalable and can accommodate any new
nodes at any time.
❑It is Flexible And Hence Open to Physical
❑All the nodes can be accessed by
Centralized Monitoring System.
❑It is Wireless.
❑As it is wireless, it is prone to hackers.
❑Can not be used for high speed
❑It is Expensive Network.
❑If Star Topology is used, failure of central
node leads to whole network shutdown.

We analyzed the major technical challenges as well as the research issues in designing hardware
architectures, mobility, algorithms, and protocols for the large-scale MWSNs.
We discussed about mobile sensor node architecture, mobility, topology, and routing protocols.
And Finally discussed about the market value of the MWSNs.
