  • Distributed reaction mechanisms to prevent selfish misbehavior in wireless Ad Hoc networks 

    Jaggi, Neeraj; Giri, Vamshikrishna Reddy; Namboodiri, Vinod (IEEE, 2011-12-05)
    We address the issue of misbehavior detection and reaction in IEEE 802.11 based Ad Hoc networks. Selfish misbehavior involves disobeying standard protocol mechanisms to gain unfair access to the channel at the expense of ...
  • Dynamical adjustment of block replacement algorithms 

    Walterscheidt, U.; Pendse, Ravi (IEEE, 1998-03-08)
    Block replacement algorithms are an important component of any cache controller, specially for disk caches. In recent years, complex and sophisticated algorithms have been developed, that reduce the miss-rate of disk caches. ...
  • EM-AODV: Metric based enhancement to AODV routing protocol 

    Thanthry, Nagaraja; Kaki, S.R.; Pendse, Ravi (IEEE, 2006-09-25)
    Needless to say the importance of mobile ad-hoc networks has been increasing everyday because of its infrastructure-less, decentralized nature. Performance of an ad-hoc network mainly depends upon factors like path selection ...
  • A novel graphical technique for analysis of runtime cache behavior 

    Pendse, Ravi; Tambe, N.; Walterscheidt, U. (IEEE, 1997-08-06)
    A novel technique is introduced to graphically analyze the runtime behavior of block replacement algorithms used in cache controllers. The new method allows a behavioral comparison of two or more algorithms, previously ...
  • Selective prefetching: prefetching when only required 

    Pendse, Ravi; Katta, H. (IEEE, 1999)
    Cache memories are commonly used to reduce the number of slower lower-level memory accesses, thereby improving the memory hierarchy performance. However, high cache miss-ratio can severely degrade system performance. It ...
  • Statistical estimation of route expiry times in on-demand ad hoc routing protocols 

    Arbindi, Srividya; Namuduri, Kameswara; Pendse, Ravi (IEEE, 2005-11-07)
    On-demand routing protocols discover routes only when the source node has a packet to send to the destination. These protocols cache previously discovered routes in order to reduce the routing overheads as well as to ...
