  2. 2. CONTENTS ➢What is MWSNs? ➢Mobile Sensor Node Architecture ➢Design Challenges Of MWSN ➢Challenges Faced By MWSNs ➢Mobility Models ➢ Network Topology ➢Routing Protocols ➢LEACH Variant ➢T-LEACH Variant ➢Merits / Demerits ➢Applications ➢Impact On Financial World ➢Conclusion
  3. 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. 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. 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. 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. 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. 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. 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. WSN Routing Protocol Node Centric Routing Protocol Data Centric Routing Protocol Source Initiated Routing Protocol Destination Initiated Routing Protocol
  10. 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. 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. 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. 13. Applications ➢Military Applications ➢Area Monitoring ➢Transport Applications ➢Surveilance System ➢Self–Driving Cars
  14. 14. Impact On Financial Market ➢ Wireless Sensor Network Market size was valued at USD 56.24 Billion in 2020. ➢ It is projected to reach USD 215.93 Billion by 2028, growing at a CAGR of 18.32% from 2021 to 2028. ➢ Intel Corporation Huawei Investment & Holding Co., Ltd., Dell Incorporation, Texas Instruments Inc., Cisco Systems Inc., Hewlett Packard Enterprise Co., NXP Semiconductors N.V., STMicroelectronics N.V., TE Connectivity Ltd., Advantech Co., Ltd.
  15. 15. Conclusions 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.
