ajustar a distância entre as linhas e repetir o cabeçalho em cada página?

Question

Eu enfrentei um problema em longtable, como cada coluna é longa, ela é impressa em uma página como mostra a imagem, e também quando vai para a próxima página precisa repetir o cabeçalho da primeira linha.

\documentclass{article}
\usepackage[english]{babel}
\usepackage{longtable}
\usepackage{microtype}
\usepackage{ragged2e}
\usepackage{array}
\usepackage{lscape}
\usepackage{caption}
\newcounter{temp}
\newcommand{\first}{\setcounter{temp}{1}\thetemp- }
\newcommand{\following}{\stepcounter{temp}\par\thetemp- }

\begin{document}

            \hline
            \textbf{Wormhole types} & \textbf{Encapsulation} & \textbf{Out of Band} & \textbf{High Power} & \textbf{Packet Relay} & \textbf{Protocol Deviations} \\\hline

            & \first there is a smaller probability of RREQ being discarded than other RREQs which are repeatedly received by intermediate nodes.
                \following RREQ packet arriving to destination, does not keep middle nodes as hops, and then it appears to have passed through minimum number of hops.

Para repetir títulos, use \endfirstheade \endhead. Para aumentar o espaço entre as linhas, você pode usar makecelle dentro \setcellgapsde \makegapedcellsum grupo. Você não precisará centerdo ambiente longtalecentralizado por padrão. Aliás, sua mesa não cabe na largura (e eu não corrigi).
