3. 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.

4. Mobile Sensor
Node Architecture
➢ Designed with one or more
sensors.
➢ 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.

5. Design Challenges Of MWSNs
➢ Hardware Cost
➢ System Architecture
➢ Memory
➢ Battery Size
➢ Processing Speed
➢ Sensor Node / Sink Mobility
➢ Coverage
➢ Wireless Connectivity
➢ Programmability
➢ Security
➢ Protocol Design
➢ Data Redundancy
➢ Energy Consumption

6. Challenges Faced By MWSNs
HARDARE
➢Limited battery power.
➢Low-cost requirements.
➢Low complexity algorithms required for
microcontrollers.
➢Use of only a simplex radio.
ENVIRONMENTAL
➢Shared medium
➢Varying topology
➢Hybrid topology is the solution for data
collection, network performance and
varying topology.

7. Mobility Models
➢ Modeled to describe the
movement towards/away mobile
sensor nodes.
➢ 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.

8. Network Topology
➢ Transfer the data onto the mobile
sensor nodes to the sink/base
station..
➢ Then, The sink and the remote
user/server are connected by the
internet.
➢ MWSNs purely depend on Data
Collection or Topology
Management Scheme.
➢ 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 group.
SensorNode

9. Routing Protocols
➢ 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.

10. LEACH
(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
sensor nodes
➢ 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.

11. T-LEACH Variant
➢ It uses the Hierarchical Tree Topology.
➢ There are two phases
➢ Topology Construction Stage
➢ Data aggregation tree
➢ Cluster structure
➢ Multi-hop transmit
mechanism
➢ Topology Maintenance Stage.
➢ Follows Multi-Hop Scheme
➢ Member Nodes Mobile
Reaction Mechanism.
➢ Cluster Mobile Reaction
Mechanism.
➢ T-Leach is Efficient Than Leach in
terms of packet delivery ratio and
average energy consumption.

12. MWSNs
MERITS
❑Scalable and can accommodate any new
nodes at any time.
❑It is Flexible And Hence Open to Physical
Partitions.
❑All the nodes can be accessed by
Centralized Monitoring System.
❑It is Wireless.
DEMERITS
❑As it is wireless, it is prone to hackers.
❑Can not be used for high speed
communication.
❑It is Expensive Network.
❑If Star Topology is used, failure of central
node leads to whole network shutdown.

13. Applications
➢Military Applications
➢Area Monitoring
➢Transport Applications
➢Surveilance System
➢Self–Driving Cars
