Heterogeneous Wireless Mesh Networks (HetMesh) is a promising high throughput technology for multi-hop data forwarding by mobile clients and backbone routers in a dynamic environment. HetMesh supports Wifi-Direct facility and other separate access technologies in its mobile clients, which makes the selection of a suitable next hop forwarder for data transmission challenging. This paper proposes a...
Event driven data gathering or convergecast through sensor nodes requires efficient and correct delivery of data at the sink. A tree rooted at the sink is an ideal topology for data gathering which utilizes sensor resources properly. Resource constrained sensor nodes are highly prone to sudden crash. A set of algorithms, proposed in this paper, builds a data gathering tree rooted at the sink. The...
