In the last decade, both mobile and multimedia communications have experienced unequaled rapid growth and commercial success. However, transmitting multimedia flows over wireless Ad hoc network remains an extremely challenging issue due to the limited battery lifetime of the wireless nodes. The focus, of this paper, is to design a new efficient protocol optimizing the energy consumption when transmitting video streams. We propose to exploit the SVC coding to adapt dynamically the received video quality to the instantaneous wireless nodes' characteristics. This is achieved through determining the number of the transmitted/received enhancements layers of an SVC video based on the wireless node context. The proposed solution also considers the routing aspects to guarantee to destinations the requested QoS. In order to evaluate the performance of our scheme, we have carried out several sets of simulation experiments. Our results indicate that our proposal outperforms the conventional approach by increasing the overall network lifetime while maintaining a high perceived video quality.Index Terms-wireless ad hoc networks, multimedia streaming, energy efficiency, transmission/reception power.

In this paper we propose a new framework able to ensure security, multimedia quality and energy efficiency in Multimedia Wireless Sensor Networks (MWSNs). The energy is an important and limited resource, which has a direct impact on the lifetime of nodes in MWSNs. In addition, the characteristics of MWSNs like the limited bandwidth and non-deterministic channel access have a significant impact on the QoS of multimedia traffic. We propose the Efficient Dynamic Selective Encryption Framework (EDES) in order to reduce the energy consumption and increase the QoS while ensuring a secure multimedia traffic. EDES proposes three security levels (high, medium and low) and the selection of each level depends on the energy and QoS parameters. Moreover, the cross-layer approach is selected for EDES to take into account the different parameters at physical, MAC and upper layers. The capacity metric is proposed to evaluate the possibility to increase or decrease the security level. The simulation results illustrate the importance of the security level adaptation according to the QoS and the energy parameters. EDES increases the lifetime duration of nodes by almost 40% compared to static encryption.

The security of multimedia data in Wireless Ad hoc Networks (WANet) is commonly provided by encryption, which consists in transforming a plain text message into an unintelligible ciphertext. Nevertheless, the classical and modern ciphers have all been developed without taking into consideration the intrinsic characteristics of multimedia flows. In this chapter, the author proposes to reduce the computational requirements for the multimedia flow’s encryption when the energy is a limited resource, as it is the case of WANets. Thus, the chapter defines a new profile of Secure Real Time Protocol (SRTP), named EE_SRTP. EE_SRTP provides energy efficiency to SRTP, which provides essentially confidentiality, message authentication, and replay protection to the RTP traffic. In EE_SRTP, the author exploits the dependency existing between the frames created by the inter-frame coding to further improve the energy-efficiency of the encryption process. In contrast with the existing approaches, this chapter presents an experimental model that integrates EE_SRTP to Video LAN Coding (VLC). Therefore, to validate EE_SRTP, the author implements a secure version of VLC (SecVLC). The performance evaluation demonstrates clearly that using this new scheme in the context of wireless ad hoc nodes allows saving energy while ensuring a high level of content confidentiality, without adding an overhead to the wireless network.
