PROJECT TITLE :

A Hybrid Multicast Routing for Large Scale Sensor Networks with Holes

ABSTRACT:

In this text, we gift RE MR, the first hybrid multicast routing protocol that builds on the strengths of existing topology-based mostly, hierarchical and geographic multicast solutions, whereas addressing their limitations. In RE MR, the multicast path search drawback is formulated as the capacitated concentrator location downside (CCLP) that yields the network topology that minimizes the sum of path lengths from the multicast root to multicast members. Furthermore, its trajectory-based mostly lightweight hole detection (THLD) discovers deployment area irregularities (i.e., network holes) that have an effect on its resolution and autonomously take them into consideration to come up with updated routing ways, and its Energy-efficient Packet Forwarding (EPF) and Multi-level Facility Computation (MFC) cut back computational and communication overheads. We have a tendency to implement RE MR in TinyOS and evaluate it extensively using TOSSIM for comparatively giant-scale simulations (400 nodes); we tend to conjointly implement RE MR on real-hardware and perform experiments on a testbed consisting of 42 TelosB motes. Through the simulations and experiments on real-hardware, we have a tendency to demonstrate that RE MR reduces the energy consumption by up to 57 per- ent and the top-to-finish delay by up to 8 %, compared with the state-of-the-art multicast routing protocols.
