Dynamic index coding for wireless broadcast networks
Abstract— We consider a wireless broadcast station that transmits packets to multiple users. The packet requests for each user may overlap, and some users may already have certai...

An Approximation Algorithm for Broadcast Scheduling in Heterogeneous Clusters
Network of workstation (NOW) is a cost-effective alternative to massively parallel supercomputers. As commercially available off-theshelf processors become cheaper and faster, it...

Two-Tiered Constrained Relay Node Placement in Wireless Sensor Networks: Efficient Approximations
In a wireless sensor network, short range multihop transmissions are preferred to prolong the network lifetime due to super-linear nature of energy consumption with communication d...

Efficient broadcasting using network coding
Abstract-- We consider the problem of broadcasting in an adhoc wireless network, where all nodes of the network are sources that want to transmit information to all other nodes. Ou...

Distributed Successive Approximation Coding using Broadcast Advantage: The Two-Encoder Case
Abstract-- Traditional distributed source coding rarely considers the possible link between separate encoders. However, the broadcast nature of wireless communication in sensor net...
