1. Design of energy-efficient routing protocol in multicast ad-hoc mobile networks using directional antennas J. seetaram, Assoc.prof., Sreechaitanya college of engg., karimnagar

2. Confined area • One important characteristic of ad-hoc network is that nodes are energy constrained. • A node in ad-hoc network consumes energy when transmitting, receiving, processing data, or listening to the channels. • The energy expenditure of a node can be managed at physical layer, MAC layer, network layer and transport layer. • I interested in energy conservation through the use of appropriate routing and scheduling protocols at the network layer.

3. Problem statement • In mobile ad-hoc networks a multicast packet is delivered to multiple receivers along a network structure such as a tree or mesh. • The network structure is fragile due to node mobility, and thus some members may not be able to receive the multicast packet which results in reduced packet delivery ratio. • To improve the packet delivery ratio ,multicast protocols in MANETs usually employ control packets to periodically refresh the network structure.

4. Problem statement cont., • Mesh-based protocols are more robust to mobility than tree-based. • But multicast mesh may perform worse in terms of energy efficiency and reduces network life time. • In order to maximize the lifetime of a network we need to design an energy efficient algorithms for routing and scheduling with nodes in the network use single directional antennas.

5. Design methodology • Directional antennas can be useful in significantly increasing node and network life time. • In order to utilize directional antennas, an algorithm is needed that will enable nodes to point their antennas to the right place at right time. • By using this algorithm the total energy consumption is decreased and thus increases network lifetime by a factor, which is proportional to the antenna gain.

6. Design methodology cont., • In addition, I plan to improve 50% in network lifetime that is achieved by using energy-aware routing, instead of conventional routing. • In energy-aware routing protocol the idea is to route packets through nodes that have sufficient remaining energy, rather than through nodes whose energy is nearly depleted. • Furthermore , I plan to propose a method that can enable scheduling algorithm to work in a distributed and adaptive fashion. • I plan to incorporate proposed algorithm into ns-2 simulator or Qualnet.

7. THE FOLLOWING PARAMETERS ARE TO BE ANALYZED IN PROPOSED ALGORITHM: • The average residual energy remaining at the nodes when all packets have been evacuated from the network. • The variance of the node residual energies. • The time when a node runs out of energy. • The average number of hops on the paths taken by the packets. • The received-to-sent packet ratio. • The number of collisions suffered by the packets, due to the MAC protocol and the hidden terminal packets.

8. Applications of proposed algorithm • Remote Water sensing driven metering and communication for water distribution systems by using sensor ad-hoc networks.

9. Additional Research areas • Optimisation of Data Mining techniques for geospatial data and signal data for deploying mobile devices. • Remote sensing Image Carving techniques for deployment on mobile devices without loosing its fidelity.
