Customization aims to improve the performance of pure object-oriented languages by compiling multiple copies of a source method, each of them specialized for a certain revceiver type. Like other code duplication techniques, it gains performance by trading code space for better speed. Unfortunately, customization can significantly increase code space, especially for larger programs. We show that...

The fairness of Stochastic Fairness Queuing (SFQ) is greatly affected by the number of queues to which flows are hashed. Specifically, a large queue pool results in a small probability of flow collisions and, hence, better fairness in allocating bandwidth to flows. However, the research community has assumed that a large number of queues poses an unsustainably large overhead on an SFQ router, e...

The wide di usion of Java is partly due to its mechanisms for mobile computing. Java provides most of the functions required to implement mobile applications, essentially code mobility (i.e., dynamic class loading) and data mobility (i.e., object serialization). However, Java does not provide any mechanism for the mobility of the computation (i.e., threads migration). Several projects have addr...

Continuation-passing style (CPS) is often criticized to be more expensive than the usual direct style of functional programming. By structure, CPS functions indeed are passed one extra argument (the continuation), and each intermediate result indeed occurs in a function call (to the continuation). As higher-order functions, continuations are also more expensive. However, by structure also, CPS ...

The establishing of a pairwise key between two nodes for encryption in a wireless sensor network is a challenging issue. To do this, we propose a new deterministic key pre-distribution scheme which has modified the multiple key space scheme (MKSS). In the MKSS, the authors define two random parameters to make better resilience than existing schemes. Instead of a random selection of these parame...

Abstract- Efficient message delivery in city environment is required to ensure driver’s safety and passenger’s comfortability. In cities of developed nations, routing of data in vehicular Ad hoc Network (VANET) faces many challenges such as radio obstacles, mobility constraints and uneven nodes distribution. These factors primarily makes communication between vehicles complex. To overcome and t...

Routing is one of the challenging issues in Mobile Ad hoc NETw orks (MANETs). Broadcasting is the fundamental and eff icient data dissemination mechanism for route discovery in reactive routing protocols of Mobile Ad hoc NETw ork (MANET). This causes the problem called the broadcast storm problem w hich results in redundant retransmission and adds to routing overhead. There are many approaches ...
