Conclusion


Introduction (SRTLD) in Wireless Sensor Network (WSN)


Wireless Sensor Network (WSN) (SRTLD) in Wireless Sensor Network (WSN)

  • WSN is a wireless ad hoc network that composes of a large number of sensor nodes, which are densely deployed either inside the event area or very close to it.

  • Each sensor node has one or many different types of sensors. Each node is physically small, with limitation on power, memory and processing capabilities,


Low power signal processing (SRTLD) in Wireless Sensor Network (WSN)

Low power computation

Short-range communications capabilities

Modest irreplaceable energy budget

Linked by some wireless medium: radio, infrared, ultrasound, etc.

Sensor Node features


Types of sensors (SRTLD) in Wireless Sensor Network (WSN)

  • Pressure

  • Temperature

  • Light

  • Bio-sensors

  • Chemical

  • Acoustic

  • Accelerometers

  • Seismic

  • Metal detectors

  • Personal motion detectors


WSN and IEEE 802.15.4 (SRTLD) in Wireless Sensor Network (WSN)

  • The IEEE 802.15.4 protocol specifies the Medium Access Control (MAC) sub-layer and physical layer

  • Targets for Low-Rate Wireless Private Area Networks (LR-WPAN) with low power consumption, low cost wireless networking that fits the requirements of WSN.

IEEE 802.15.4 Message Structure (SRTLD) in Wireless Sensor Network (WSN)

  • Message frame type:

    • Data

    • Acknowledgement

    • Beacon

    • MAC


Network Topologies (SRTLD) in Wireless Sensor Network (WSN)

  • WSNhas a peer-to-peer topology and a star topology.

  • A peer-to-peer topology consists of sensor nodes that are connected with each other without infrastructure. Since the nodes in a network can serve as routers and devices, they can forward the packets on behalf of the other nodes.

Peer-to-peer topology


  • A star (SRTLD) in Wireless Sensor Network (WSN) topology consists of coordinator (PAN) sensor node and number of sensor devices which only communicate with its coordinator. The PAN coordinator dispatches the sensory data to the destination.

Star topology


Why real time communication in wsn

The sensory data is valid only for a limited time duration, and hence needs to be delivered within such time bound called deadline

WSN demands real-time communication which means messages in the network are delivered according to their end-to-end deadlines (packet lifetime)

Why Real-Time communication in (WSN)


Why security in wsn
Why Security in WSN and hence needs to be delivered within such time bound called deadline

  • Security is the most difficult problem to solve in WSN due to limitation in memory, processing and power.

  • Network layer attacks

    • manipulating routing information,

    • selective forwarding,

    • Sybil,

    • sinkhole,

    • wormhole, and

    • Hello flooding (unidirectional) attacks


Problem statement
Problem Statement and hence needs to be delivered within such time bound called deadline

  • WSNs are restricted to limited memory, processing and power

  • WSNs have unreliable links and highly unpredictable communication delays due to

    • limited bandwidth, and

    • link quality heavily influenced by environmental factors.

  • WSN applications must operate for months or years without wired power supplies.

  • The important data must delivery within real-time

  • WSN routing protocols are quite simple, and for this reason are susceptible to several kinds of attacks


Objective
Objective and hence needs to be delivered within such time bound called deadline

  • To develop security in the proposed real-time routing.

  • To develop low rate WSN that will achieve high delivery ratio while utilizing low packet overhead and low power consumption.

Routing in wsn
Routing in WSN and hence needs to be delivered within such time bound called deadline

  • Challenges

    • It is not possible to build a global addressing scheme for the deployment of a large number of sensor nodes as the overhead of ID maintenance is high.

    • Position awareness of sensor nodes is important since data collection is normally based on the location.

    • Data forwarding and data redundancy

    • Power consideration (minimize broadcasting)

    • Security

  • Classification of routing protocol based on structure

    • Flat network

    • Location-based

    • Hierarchical

  • Network holes problem

  • If the diameter of the hole is smaller than the transmission range at the maximum power, then SRTLD will identify a maximum transmission power that is sufficient to transmit the packet across the hole.

Maximum size of neighbor table is 300 bytes (20 sensor nodes)


4. Power Management and hence needs to be delivered within such time bound called deadline

  • Sleeping mode is used to save the power.

    • If the sensor nodes reply to neighbour discovery beacons, they will not sleep until the session of routing is finished (not receive neighbour discovery beacons for two periods time)

Conclusion and hence needs to be delivered within such time bound called deadline

WSN applications require delivery of various types of sensory data with different levels of real-time requirements because the sensory data is valid only for a limited time duration.

This research proposesSRTLD which is a novel real-time routing protocol which combines link quality, remaining power, packet velocity and securityin WSN

SRTLD will prolong network’s lifetime using distribution load forwarding.

SRTLD will provide efficient power consumption, high packet delivery ratio and minimum control packet overhead in WSN.
