  • Cross-layer analysis of route discovery process in saturated ad hoc network 

    Shah, Hardik Dinendra (Wichita State University, 2011-05)
    This thesis presents a detailed analysis of the route discovery process in saturated ad hoc networks. The causes and consequences of this process are described in terms of medium access control (MAC) delays and routing ...
  • Crucial edge detection in sensor system under energy constraints 

    Madhvesh, Ashok (Wichita State University, 2009-12)
    Wireless sensor nodes are usually deployed in remote locations for various applications that require monitoring of certain interesting events. Due to this remote operational feature the longevity of the sensor node's ...
  • Data caching in ad hoc networks using game-theoretic analysis 

    Dang, Hoang (Wichita State University, 2011-05)
    There have been researches that studied selfish data caching in ad hoc networks using game-theoretic analysis. However, due to the caching problem’s theoretical root in classic facility location problem and k-median problem, ...
  • Data preservation in intermittently connected sensor network with data priority 

    Xue, Xinyu (Wichita State University, 2013-05)
    In intermittently connected sensor networks, the data generated may have different importance and priority. Different types of data will help scientists analyze the physical environment differently. In a challenging ...
