CSE730x Research Seminar

• Instructor: Prof. Chenyang Lu
• Time: Thursday at 3pm-4:00pm, Location: Bryan 509C
• Google group: google group

This seminar examines fundamental and emerging concepts in concurrency and distribution by studying seminal papers and recent research results. Broad topics of interest include models of concurrency, mobile computing, parallel architectures, sensor networks, distributed algorithms, and specialized protocols. Each semester, the seminar emphasizes different themes reflecting the current research interests of the participants.

The theme of this semester's seminar is Wireless Sensor Networks. We will read and discuss papers from recent major conferences on mobile, wireless, and sensor networks and systems. These conferences include:

• SenSys ([1])
• IPSN ([2])
• Sigcomm ([3])
• MobiCom ([4])
• MobiSys ([5])
• NSDI ([6])
• SOSP ([7])
• OSDI ([8])
• RTSS ([9])
• RTAS ([10])
• Wireless Health ([11])
• BodyNets ([12])
• BSN ([13])

Low Power, Low Delay: Opportunistic Routing meets Duty Cycling

Traditionally, routing in wireless sensor networks consists of two steps: First, the routing protocol selects a next hop, and, second, the MAC protocol waits for the intended desti- nation to wake up and receive the data. This design makes it difficult to adapt to link dynamics and introduces delays while waiting for the next hop to wake up. In this paper we introduce ORW, a practical opportunis- tic routing scheme for wireless sensor networks. In a duty- cycled setting, packets are addressed to sets of potential re- ceivers and forwarded by the neighbor that wakes up first and successfully receives the packet. This reduces delay and energy consumption by utilizing all neighbors as potential forwarders. Furthermore, this increases resilience to wire- less link dynamics by exploiting spatial diversity. Our re- sults show that ORW reduces radio duty-cycles on average by 50% (up to 90% on individual nodes) and delays by 30% to 90% when compared to the state of the art.
