Peer-to-peer (P2P) networks are becoming very popular since various applications such as media streaming and voice over IP use these networks in different environment settings without the need for a client-server structure. P2P protocols have been originally designed for traditional wired networks, and when deployed in wireless network environments, several challenges are encountered. For instance,...
Load balancing in data centers have been a common practice in the last couple of decades. This has been done statically in traditional networks with little or no feedback information from the underlying network state. With the current large cloud data centers and continuous changing traffic patterns, the drive for more interactive and dynamic solution to reduce the latency and improve the network...
Cloud computing has empowered the individual user by providing seemingly unlimited storage space and availability and accessibility of data anytime and anywhere. Cloud service providers are able to maximize data storage space by incorporating data deduplication into cloud storage. Although data deduplication removes data redundancy and data replication, it also introduces major data privacy and security...
In recent years, multimedia network services have moved from a single service to rich services which integrate multiservice capabilities integration. If all service requests require the user to send the request by himself, this will result to a huge control function load and complex service collaboration. In order to address service interaction and reuse the service capability, 3GPP proposes a Service...
The design of complex software systems is a challenging task because it involves a wide range of quality attributes such as security, performance, reliability, to name a few. Dealing with each of these attributes requires specific set of skills, which quite often, involves making various trade-offs. This paper proposes a novel Model-Driven Software Performance Engineering (MDSPE) process that can...
The performance analysis of distributed software systems is a challenging task in which the assessment of performance measures is a vital step. Due to its versatility, the concept of software performance engineering (SPE) has been advocated as a promising solution towards realizing that step. This paper illustrates how by using our recently proposed Model-Driven SPE (MDSPE) approach, one can design...
